1. Introduction
This article addresses the urgent need to rethink deindustrialized urban spaces, where former industrial buildings pose challenges for heritage, identity, and local regeneration. Small- and medium-sized cities, as exemplified by Komotini—a medium—sized city in Northeastern Greece—face legal, ownership, and resource constraints that often prevent public-led transformation of protected industrial sites. These constraints make it necessary to develop low-cost, replicable design approaches that reconnect communities with industrial legacies while delivering accessible urban amenities. We should also highlight the importance of research on industrial heritage in Greece and the regeneration of surrounding spaces. Although former industrial sites are protected by national law, their transformation is often hindered because ownership is typically held by private stakeholders rather than public authorities.
Grounded in a field research case study of the square in front of the Technical Chamber of Greece (a former tobacco warehouse), this article proposes a design strategy that integrates semiotics, psychogeographic methods, and industrial heritage preservation. It also incorporates elements from our design proposal presented at the Panhellenic Architectural Ideas Design Competition organized by the Regional Unit of Thrace of the Technical Chamber of Greece in spring 2025. The proposal received second place. The proposal, tested through participatory drifting walks and socio-historical analysis, aims to use architectural traces to guide movement, frame recreational activities, and generate new collective narratives. By producing an urban palimpsest that preserves tangible fabric and intangible memory, the study demonstrates how adaptive reuse focused on accessibility, affordable programming, and choreographed movement can reactivate industrial heritage as a resilient public resource that strengthens community identity and local economies.
Semiotics, psychogeography, and industrial heritage preservation form a complementary theoretical triad for reading former industrial landscapes. Semiotics supplies a vocabulary for decoding the material signs embedded in industrial buildings that communicate past functions and social relations. Psychogeography foregrounds the experiential dimensions of place by tracing how memory and perception produce meaning in everyday use. Its methods (drifting and mapping of emotional responses) reveal routes, points, and edges that conventional plans often miss. Industrial heritage preservation anchors these interpretive practices in the physical reality of surviving fabric, insisting on the conservation of tangible elements and the intangible narratives they carry. Together, these approaches enable designers and planners to treat industrial sites not as inert monuments but as legible texts with signs that can be read and reconfigured.
Applied to adaptive redesign, the three frameworks guide both diagnosis and intervention. Semiotic analysis identifies which industrial elements can act as spatial organizers, psychogeographic inquiry prioritizes routes and atmospheres that resonate with local users, and preservation principles set thresholds for intervention that retain authenticity and allow new uses. This synthesis supports low-intervention strategies that activate public life, encourage collective stewardship, and catalyze incremental economic activity. The result is an adaptive redesign model that privileges social value, accessibility, and the production of new everyday practices over purely aesthetic or market-driven outcomes.
Despite their generative potential, these theories face practical and epistemological limits when deployed in a specific domain, such as in the case study of paper, which focuses on the redesign of a public space in front of a former industrial building. In the case study, the use of semiotics and psychogeography techniques can be criticized for subjectivity and limited reproducibility, as affective mappings reflect particular participants and moments and do not capture broader experiences. At the same time, preservation constraints exist, for example, legal protection for the safeguarding of industrial buildings and ownership regimes that circumscribe a range of feasible interventions. This means that in the case study of the Technical Chamber Square in Komotini, it was necessary to interpret the theoretical framework with the institutional and technical capacity frameworks to use the above theories in the adaptive redesign of the public space in front of the Technical Chamber building.
1.1. The Semiotics Approach
Semiotics views material artifacts as active agents within networks of meaning, where significance is continually shaped and reshaped by cultural codes and interpretive acts [
1]. Invoking Eco’s model of cultural codes, Barthes’s analysis of myth and signification, and Peirce’s triadic theory of the sign provides a semiotic toolkit for adaptive redesign, enabling designers to decode industrial fabric as layered systems of meaning and craft interventions that communicate new functions while preserving historical identity. Eco’s perspective emphasizes that signs operate within codes, allowing both direct reference and multiple layers of meaning. This insight is crucial for understanding how industrial sites communicate cultural identity [
2]. Barthes illustrates that ordinary urban elements can acquire symbolic power, reinforcing dominant narratives. In industrial heritage, architectural details may, therefore, embody ideological significance beyond their practical function [
3]. Peirce’s semiotic framework suggests that heritage meaning is not static but emerges through the interplay of symbols, their referents, and the interpretations communities construct around them. A Peircean perspective underscores the dynamic process by which stakeholders, former workers, municipal authorities, developers, and visitors generate successive interpretants that alter the relationship between object and meaning over time [
4].
Combining the theories of Eco, Barthes, and Peirce highlights three essential steps for research and practice. First, integrate material with semiotic analysis: documentation should combine technical surveys and physical assessments with detailed catalogs of signs, inscriptions, and assemblages that influence how the public interprets a site [
5]. Second, recognize multiplicity and contestation as important sources of insight: mapping different interpretations, such as workers’ memories, heritage tourism stories, or investor perspectives, uncovers tensions that policy must address rather than ignore [
5]. Third, explore the temporality of interpretation through long-term methods such as archival research, oral histories, and repeated experiential walks, which demonstrate how meanings change, fade, or are intentionally redefined over time [
2,
4].
From a practical standpoint, these theoretical commitments suggest specific design and management strategies. Adaptive reuse should preserve the semiotic integrity of meaningful sign-vehicles, such as processual elements, circulation patterns, and vantage points, while programming activities that create new interpretants aligned with social utility and inclusivity [
6]. Interpretation programs should deliberately expose ambivalence and multiplicity rather than smoothing pasts over single heritage myths [
3]. In summary, treating industrial heritage as a semiotic field aligns material conservation with democratic meaning-making. The longevity and social significance of preserved industrial fabric depend on maintaining dialogic relations between the object and interpretant over time, allowing communities to continue to repurpose the semiotic resources of place [
7]. Semiotic readings of industrial fabric are complemented by the psychogeographic theory in order to map how movement and affect animate those signs.
1.2. The Psychogeographic Approach
Debord defined psychogeography as the study of how geographical environments influence emotions and behaviors, a perspective that continues to inform contemporary urban design [
8]. Debord’s psychogeographic theory, centered on dérive and detournement, is inscribed into adaptive redesign by revealing affective urban flows and latent routes within industrial ruins, thereby guiding interventions that reorient circulation, perception, and collective appropriation toward socially productive uses. According to Debord, a departure from the capitalist mechanism, a spectacle that transforms individuals into beings defined solely through consumerist fantasies and representations, can be realized only through a
situationist revolution, the activation of creative and participatory methodologies that would ultimately restore authenticity to lived experience [
9,
10,
11]. In our research, we primarily focus on its implementation in the architectural and urban design field. It would thus be a significant omission not to address the interconnection between
spectacle,
architecture, and
urban design as articulated in Debord’s work. Within this context, Debord develops the notion of
unitary urbanism, emerging from psychogeographical experiments that prefigured later and contemporary phenomena—such as cyberspace and the politics of simulation.
In Debord’s unified urbanism, urban space is conceived as a canvas of constraints upon which social and cultural components are inscribed. Central to his theory is the dérive—a form of exploratory wandering guided by atmospheres rather than planned routes, revealing hidden emotional geographies [
12]. This approach demonstrates that industrial heritage sites can be reactivated by encouraging new forms of movement and perception, transforming them into spaces of collective exploration.
The legacy of Debord’s theory in architecture and artistic production lies in establishing the principle that, within a revolutionary and collectively driven framework, politics, art, and aesthetics must not be treated as distinct or autonomous domains. In other words, the individual pursuit of political and cultural subversion of the capitalist mode of societal organization can only take root if accompanied by a structural revolution and a parallel critique of everyday life—its production, architecture, art, and ethics alike. Hence, only through a holistic and collective approach—as emphasized in
The Society of the Spectacle—can critique address the organization of “
social time” and “
spatial form” [
13].
Perhaps more than anywhere else, this condition is reflected, on a secondary level of interpretation, in contemporary theoretical approaches to the reading and design of urban space. Today, the urban environment is no longer conceived merely as an empty or full space—as it was within earlier artistic and architectural movements such as Modernism or the Bauhaus—but rather as a complex structure: a network of social, ecological, and cultural interdependencies hosting the fundamental relationships between humans and their environments.
Human and social presence thus emerge as essential preconditions for the formation and production of space [
14,
15,
16]. Contemporary artistic and urban design practices continue to engage with and shape the urban landscape through an ongoing process of
co-becoming: a continuous invention of urban space and a redefinition of our nomadic selves through a multiplicity of ephemeral and transient encounters [
17,
18]. Within this spectral condition, an emergent subject is implied—cognitively transformative and epistemically subversive—formed through coexistence with other subjects and objects, whether social, architectural, or technological.
Guy Debord’s psychogeographic map of Paris, presented in the form of a book titled
The Naked City, offers an evocative precedent for our approach [
19]. Debord fractured the city into islands of experience, connected by red arrows that trace the dérive routes of urban explorers (
Figure 1). Rather than a fixed blueprint, this map proposes the city as a dynamic palimpsest of emotions and behaviors. We adopted this mindset in Komotini, treating the city’s old tobacco warehouses and adjacent public spaces not as static artifacts but as living embodiments of collective memory, waiting to be reactivated through carefully choreographed movement and design. Decoded meanings and mapped affective flows derived from the semiotics and psychogeographic theories were complemented by industrial heritage preservation theories in order to anchor interventions in the tangible fabric and legal frameworks of the former industrial site.
1.3. Preservation of Tangible and Intangible Industrial Heritage
Preserving industrial heritage requires a dual focus on tangible structures and intangible legacies, as the value of these sites is created through an ongoing relationship between physical fabric and social meaning. In our study, industrial heritage preservation theories provide legal, material, and interpretive frameworks that safeguard significant fabric and intangible narratives, ensuring that the adaptive redesign interventions respect authenticity and anchor new uses within the historical urban landscape of Komotini. Material conservation preserves the reflective traces of production and patina, which support claims of authenticity and provide the spatial features necessary for reuse and interpretation [
21,
22]. Intangible elements, such as collective memories, mediate how communities and visitors interpret, inhabit, and repurpose industrial sites, shaping both the symbolic importance and the everyday functionality of interventions [
23,
24].
The balance between fabric and narrative is both methodological and ethical. Conservators and designers must document and stabilize physical conditions using established conservation science while simultaneously eliciting and recording living knowledge through ethnography, oral history, and participatory mapping. This mixed-methods approach permits preservation plans that treat fabric not as an inert relic but as a semiotic resource whose legibility depends on interpretive infrastructures that transmit meanings across generations [
25,
26]. Preserved industrial buildings and their surrounding spaces require active programming and community engagement; otherwise, they risk becoming isolated relics rather than integrated parts of the urban fabric. Adaptive reuse and redesign strategies that prioritize social utility create new interpretive layers, keeping the industrial fabric alive and meaningful [
27]. However, reuse and redesign must avoid instrumentalizing heritage solely for economic ends; projects that privilege market narratives over workers’ memories or community attachments can produce symbolic displacement and social inequity [
28]. Conservation ethics, therefore, require procedural justice: inclusive decision-making processes, transparency about trade-offs, and mechanisms for long-term stewardship co-managed by stakeholders [
29].
Interpretation plays a mediating role in sustaining the dialogic relation between object and meaning in the adaptive redesign of former industrial landscapes. Interpretive programs should be reflexive: they must acknowledge multiple temporalities and conflicting histories and provide space for dissenting memories rather than producing a monologic heritage script [
3,
30]. Digital technologies, 3D scans, oral history repositories, and augmented reality could extend accessibility and enable dynamic layering of narratives, as long as they are integrated with site-based practices that preserve embodied knowledge and sensory engagement with material form [
31].
Ultimately, securing sustainable futures for industrial sites through adaptive redesign requires an integrative conservation paradigm that treats material conservation and narrative activation as coequal aims. This paradigm privileges long-term social and ecological viability over short-term economic gain, embeds participatory governance in stewardship models, and recognizes that the endurance of industrial heritage rests not only on bricks and beams but on the continued circulation of meanings, practices, and attachments (derived from the semiotics and psychogeographic theories) that make those things worth preserving [
23,
32].
2. Materials and Methods
Our research examined how adaptive redesign can shape public space design in former industrial cities without reducing heritage to simple static relics. We introduced an integrated method that combined elements from the theories of semiotics, psychogeography, and industrial heritage preservation alongside technical necessary parameters for the design of public spaces, such as accessibility, materials, and vegetation. This approach revitalizes former industrial sites as active parts of modern urban environments. The study focused on the former tobacco warehouse in Komotini, which houses the offices of the Technical Chamber of Greece’s Thrace Department, and the nearby square. By grounding our theoretical analysis and field research in this specific urban context, we developed design proposals that address both historical narratives and current community needs.
First, we clarified key concepts that were necessary for our research and design strategy, such as industrial memory, deindustrialization, and public-space design. This ensured that our methodology rested on precise, operational definitions that were used as key elements during the phase of elaboration of plans for the Technical Chamber Square. In contemporary urbanism, adaptive redesign mobilizes industrial memory as a critical interpretive framework through which the spatial and socio-economic ruptures of deindustrialization are reconfigured into public-space typologies that both acknowledge historical materialities and enable new modalities of collective use. Industrial memory encompasses physical remnants of production, everyday routines, and the collective recollections that communities attach to industrial spaces [
32]. Public-space design means the deliberate shaping of streets, squares, parks, and thresholds to support movement, interaction, and civic life [
33]. Heritage preservation encompasses policies and interventions that safeguard material and immaterial values, while enabling adaptive use [
34]. Psychogeography denotes methods that reveal how physical environments influence emotions, behavior, and daily mental maps [
35]. Deindustrialized cities are places that have lost productive functions and now carry unique social, spatial, and economic legacies [
36]. These definitions framed our descriptive-analytic method and guided the translation of memory into design.
In our study, we used archival research, on-site observation, stakeholder interviews, and psychogeographic walks. This produced a layered reading of the former tobacco warehouse and square. Architectural analysis, based on semiotics theory, interpreted the building’s structure, circulation, and material patina as active carriers of memory, not inert artifacts. Heritage assessment cataloged tangible elements and intangible attachments to reveal the values the community assigns to the place. The descriptive phase presented a detailed account of the overlapping histories, uses, and perceptions that make up the site’s urban narrative.
The analytic phase correlated those narrative layers with measurable indicators of contemporary need: accessibility, programmatic diversity, ecological performance, and social equity. Design interventions were proposed where memory values and present necessities overlap, ensuring that preservation becomes a vehicle for ongoing use rather than mere commemoration. This evidence-based approach produced interventions that are both narratively resonant and functionally effective, avoiding the pitfall of fossilizing the past behind glass.
From the combined analysis emerged several guiding principles: conserve defining structural elements while introducing flexible uses that generate regular encounters with history, reveal the site’s different historical layers through visible traces and interpretive inserts instead of isolating artifacts, engage community stakeholders in programming to align memory work with lived priorities, adopt sustainable retrofitting strategies that reduce resource demand while showcasing historic materiality, and restore spatial permeability to reconnect the warehouse with the square and invite informal social life. Implemented in Komotini, these principles produced a public realm where industrial memory functions as a generative asset, enlivening everyday civic practice and advancing ecological and social resilience. The resulting model offers a replicable strategy for deindustrialized cities seeking to reconcile past and present through humane, durable urban design.
To ground our study in the lived realities of Komotini, we pursued three complementary approaches that together produced a richly layered reading of place. The first approach combined cartography, photography, and sketching to document the city’s industrial remnants, its existing open spaces, and the networks of circulation that shape everyday movement. In this study, cartography inspired by the psychogeographic work of Debord in Paris is employed as an interpretive tool, translating spatial relationships into diagrams that clarify urban dynamics for analysis and design. Photography served to fix the textures, light, and material patina of former industrial buildings, while sketching allowed quick, interpretive translations of spatial sequences and thresholds that photographs alone cannot capture. Through this visual and graphic work, we built a morphological database of tangible elements that anchor the later analytical phases.
The second approach turned to an analysis of secondary quantitative data sets, focusing on official statistics to map Komotini’s socio-economic structure. This approach offered a necessary counterpoint to visual observation by situating the site within demographic patterns and employment structures. Mapping professional categories and population provided measurable indicators of pressure points and opportunities in the urban system. These statistical layers allowed us to read the former warehouse and its square not as isolated artifacts but as embedded within a city whose economic trajectories and social fabric shape what preservation and design can realistically achieve.
The third strand emphasized qualitative methods that attend to experience and meaning. Our methodology combined archival research, on-site observation, stakeholder interviews, and psychogeographic walks to capture both tangible and intangible dimensions of Komotini’s industrial heritage. The interviews (20 interviews) revealed how different stakeholders value the site and what uses they imagine for it. Stakeholder interview participants were selected based on the activities developed in the neighborhood where the Technical Chamber building is located. We can find small cafeterias and restaurants, a hotel, and the offices of the Technical Chamber, as well as certain offices of lawyers and engineers. The people who were interviewed work in these sectors and are also residents of the city of Komotini. The interviews were organized in two parts: the first one referred to the former uses of the square since 1993, when the offices of the Technical Chamber of Greece were installed in the former tobacco warehouse, while the second part referred to the new uses and technical dimensions of planning to be considered in the redesign of the square. This procedure provided a comprehensive image of the uses of the public space in front of the Technical Chamber building over the last thirty years, and the local expectations from the new adaptive redesign of the public space (uses, materials, and vegetation).
Complementing interviews, we employed psychogeographic walks, a practice of moving through the city with an open attentional frame to record affective responses and spontaneous encounters. We conducted five psychogeographic walks, each consisting of five people. The composition of every group varied to maximize the emotional data that could be derived from the walks. We had: 1. a group of residents who lived in the neighborhood of the Technical Chamber building, 2. a group of residents of the city of Komotini who lived in other neighborhoods of the city, 3. a group of visitors of the city, 4. a group of students from the local Democritus University of Thrace and 5. a group of people working in the neighborhood of the Technical Chamber building. Each psychogeographic walk lasted twenty minutes, while the route was around the perimeter of the current public space, located at the center of the neighborhood. We should mention that both for the stakeholders’ interviews and for the psychogeographic walks, we did not follow a certain recording protocol, and did not ask the participants for informed consent, as they are not mandatory in Greece when the research is conducted as part of a project for a public stakeholder (in our case the research was part of our design proposal for the architectural ideas design competition organized by the Technical Chamber of Greece).
We analyzed the emotional data generated through the psychogeographic walks using an inductive coding process that translated participants’ affective responses into spatial categories. Field notes, verbal reactions, and observed behaviors were coded for recurring emotional markers—such as attraction and discomfort—which were then mapped onto the physical perimeter of the square to form comparative emotive layers. These coded signals highlighted hotspots of positive engagement, zones of tension, and transitional edges with latent potential. By cross-referencing these spatialized emotional patterns with photographs and analysis of socio-economic data, we were able to triangulate subjective experience with material and demographic evidence. The diversity of the five walking groups allowed the coding process to capture a wide emotional spectrum, ensuring that the resulting analysis reflected the differentiated perceptions of residents, visitors, students, and workers who interact with the space in distinct ways.
The qualitative data analysis followed a sequential process that began with organizing the collected material—archival documents, on-site observations, stakeholder interviews, and psychogeographic walks—into a coherent corpus. Each material was first examined independently through method-appropriate coding: descriptive for archival sources, spatial coding for field observations, narrative coding for interviews, and affective and situational mapping for psychogeographic walks. This first-cycle coding allowed the tangible elements of Komotini’s industrial heritage (such as buildings and spatial configurations) and its intangible dimensions (memories, emotions, narratives, and sensory atmospheres) to emerge clearly within each method.
In the second phase, the analysis shifted toward cross-method synthesis. Pattern coding was used to identify convergences and tensions across the different data, linking historical trajectories with present-day spatial conditions and lived experiences. Spatial and temporal triangulation—overlaying historical photos with field observations, comparing interview narratives with psychogeographic impressions- helped reveal how industrial memory is distributed, perceived, and enacted across the city. This integrative process produced a layered understanding of Komotini’s industrial heritage, enabling the identification of meaningful themes and design-relevant insights for future adaptive redesign.
The three key methodological approaches (cartography/photography, official statistics, and analysis of qualitative data) together created a multi-scalar, multi-modal understanding of Komotini’s conditions. The visual documentation established the material baseline, the data analysis located the site within broader socio-economic structures, and the qualitative work revealed lived perceptions and aspirations. By integrating these strands, we avoided privileging any single type of knowledge; instead, we generated design propositions that are both evidence-based and sensitive to the affective dimensions of memory and use. This methodological layering ensured that design proposals for the Technical Chamber Square emerge from converging lines of observation, measurement, and lived testimony rather than from abstraction or nostalgia alone.
2.1. Geography and Socio-Economic Structure of Komotini
Komotini, the capital of East Macedonia and Thrace, is a regional hub whose geography, demography, and historical specificities determine both the constraints and possibilities for reimagining industrial heritage. The city’s demographic and spatial development underscores its role as a regional hub that links Balkan overland routes with the Aegean coast (
Figure 2). The continued presence of a sizeable Muslim minority that was exempted from the 1923 population exchange between Turkey and Greece gives the urban fabric layered social and spatial logics that any heritage-driven adaptive redesign must acknowledge. These geographic and demographic conditions are not neutral backdrops but active factors that shape who uses the Technical Chamber Square, how they move through it, and what symbolic meanings the former tobacco warehouse carries for different groups.
Understanding the social composition of Komotini is essential to translating industrial memory into an inclusive, usable public space. The population divides into five socio-economic classes as summarized in the following table. This typology highlights differences in resources, daily rhythms, and place expectations that should inform programming, accessibility, and material interventions at the square in front of the former tobacco warehouse (
Table 1).
This distribution foregrounds three design imperatives that we later used in our proposal for the redesign of the Technical Chamber Square. First, public-space interventions must be functionally diverse to serve both those with disposable resources and those whose engagement with place is constrained by time, mobility, or income. The Middle group, comprising roughly forty-four percent of residents, is especially salient: their daily patterns, shift work, and seasonal employment generate particular temporal rhythms for public life that adaptive redesign of public space should recognize. Second, the Lower Middle cohort, dominated by pension-dependent seniors, anchors family networks and intergenerational uses; the design must therefore prioritize safety, shade, seating, and proximate, low-cost activities to sustain social ties. Third, the presence of unemployed youth, immigrants, and persons with disabilities in the lower class argues for barrier-free circulation, low-threshold opportunities for participation, and adaptable spaces that can host vocational training, informal markets, or community enterprise.
Translating these social readings into concrete design strategies implies more than allocating amenities; it requires aligning heritage preservation tactics with everyday needs. Conservation of the tobacco warehouse’s material patina and structural logics should operate alongside adaptive redesign that creates micro-economies and social infrastructures, workspaces for small entrepreneurs, shaded nooks for elders, and flexible stages for youth cultural events. A programmatic mix that links heritage interpretation with livelihood opportunities leverages the building’s symbolic capital to produce tangible benefits across socio-economic strata. Mobility and permeability strategies must reflect Komotini’s role as a transport node: pedestrian routes and multimodal connections will expand the catchment of the square for travelers and locals alike.
2.2. Urban History of Komotini
The urban development of Komotini shows a succession of historical processes. We can identify two important architectural periods that allow us to understand the city’s historical palimpsest. The first one dates from the era of the Ottoman Empire to 1923. During the Ottoman period, Komotini became a significant commercial and administrative center. Its location along the Egnatia Road, the main east–west route in the Balkans, contributed to this. This advantageous position enabled the movement of goods. It supported the formation of an urban core organized around religious, commercial, and civic institutions [
38]. The construction of mosques, markets, and caravanserais laid the foundation for the city’s built environment. The Eski Mosque, dating to the fifteenth century, remains a prominent example of the Ottoman architectural legacy [
39].
The most profound transformation occurred after 1923, following the compulsory population exchange between Greece and Turkey and the parallel influx of refugees from Bulgaria. The settlement of displaced populations altered both the demographic composition and the spatial organization of the city. Refugee neighborhoods were rapidly constructed, often with modest housing that reflected both economic constraints and the cultural traditions of the newcomers [
40]. These districts expanded the city beyond its Ottoman-era nucleus, creating a new urban geography that symbolized the integration of diverse populations into the Greek nation-state. The transformation of Komotini after 1923 also illustrates the broader processes of nation-building in northern Greece. The juxtaposition of Ottoman-era monuments with newly built Orthodox churches and civic institutions created a symbolic landscape in which competing historical narratives were inscribed [
41]. In this sense, Komotini’s urban fabric became a site of negotiation between continuity and rupture, embodying both the persistence of Ottoman legacies and the assertion of a modern Greek identity.
2.3. Industrial Period of Komotini and Urban Heritage
In Komotini’s historical urban transformations, an important role is played by the development of economic activities related to tobacco production and commerce in the late nineteenth and early twentieth centuries. The cultivation and processing of tobacco not only underpinned local livelihoods but also drew Komotini into expansive trade routes spanning the Balkans and eastern Mediterranean. The city’s acclaim for fine tobacco spurred the construction of warehouses, storage spaces, and distribution hubs—physical markers that altered the cityscape and signaled new economic priorities [
39,
42]. Rather than being isolated in industrial zones, these facilities were woven into residential neighborhoods, a testament to how industrial enterprise and daily life became inextricably linked, imprinting a legacy still evident in the city’s fabric.
One of the most notable examples of this industrial architecture is the building of the Technical Chamber of Greece, which is inscribed in the spatial perimeter of our case study. The former brick warehouse on Parnassos Street, constructed between 1907 and 1910, was originally designed to store tobacco. Since 1993, the building has housed the offices of the Technical Chamber of Greece’s Thrace department. Its form and geometry illustrate the adaptability of industrial architecture and how commercial structures have been reconverted to host civic functions [
40]. The warehouse embodies the intersection of commerce, architecture, and urban morphology, standing as a tangible reminder of Komotini’s industrial past while simultaneously participating in its contemporary institutional life. Scholars of industrial heritage emphasize that such buildings are not merely remnants of economic history but “active cultural assets” that contribute to collective memory and urban continuity [
43,
44].
The expansion of infrastructures related to the tobacco industry was closely tied to Komotini’s connectivity. The city’s railway line, completed in the early twentieth century, facilitated the export of tobacco and integrated Komotini into regional and international markets [
38]. Tobacco warehouses clustered near transport routes and distributor roads, creating a spatial logic that linked production sites with circulation networks. At the same time, public spaces such as Eirini Square and the historic Palaia Agora remained central to civic life, highlighting the coexistence of industrial and social functions within the urban fabric [
41].
Today, the heritage dimension of the former industrial sites is increasingly recognized. The surviving warehouses, railway-related structures, and open urban spaces inside the city form a cultural landscape that embodies both the economic vitality of Komotini’s past and the challenges of integrating industrial heritage into contemporary urban planning. Our cartographic surveys revealed zones of disconnection where the industrial past and public life have diverged, underscoring the need for heritage-led interventions in the adaptive redesign (
Figure 3). Industrial sites can serve as anchors of identity, offering opportunities to restore continuity between historical assets and everyday functions, according to the theories of industrial preservation and restoration [
44]. In Komotini, the preservation and adaptive reuse of tobacco warehouses not only safeguard architectural memory but also provide a framework for reimagining the city’s future development.
2.4. The TEE Building (Technical Chamber of Greece) and Its Surrounding Area
The Technical Chamber of Greece building, located at 6 Parnassos Street, occupies a spot where Komotini’s small-scale commerce, leisure amenities, and traces of industrial heritage intersect. Around the main square of Komotini, Eirini Square, we can find several former industrial warehouses that are nowadays either restored and converted into office and commercial buildings or are abandoned, waiting for their restoration and new functions. Since the 19th century, the neighborhoods of TEE and Eirinis Square have been used for commercial and leisure activities combined with housing units [
45]. The area features local shops, cafeterias, and restaurants that encourage intermittent public gatherings, particularly in the warmer seasons. Eirini Square, a hub for outdoor socializing and overflow from dining venues, imparts a seasonal tempo to the plaza before the TEE façade: vibrant during peak times but frequently quiet at others. This highlights a disconnect between the area’s historic built environment and its ongoing urban activity. While the chamber building remains a visual and historical landmark, the surrounding public space lacks the programming and flexible infrastructure needed for continuous community use. Interviews with business owners and users showed a clear interest in the redesign of the public space in front of the Technical Chamber building, focusing on more open-air events, exhibitions, and adaptable seating options to encourage activity during evenings and less busy seasons. Introducing simple infrastructure to support flexible programming was revealed as a strategy in our design proposal that could enhance both commercial life and the presently underused forecourt of the chamber.
The TEE building’s materiality and form physically embody Komotini’s industrial past. A former tobacco warehouse, it was purchased by the Technical Chamber of Greece and restored to house its offices in the region of Thrace. Its original owner, Ioannis Stergiou, was an influential tobacco merchant of Epirus origin active between 1875 and 1925. The building’s solid fired-brick walls, neoclassical ornamentation, and distinct façade form have been preserved under the Ministry of Culture’s designation as a historic monument (FEK 112/B/21-02-1992). In its original form, the warehouse was three-storied, with a semi-basement and double-pitched roof. The construction materials of the building were stone and wood for the floors and supports, while bricks were also used for the walls. The large windows ensured good natural lighting and ventilation of the warehouse. The tobacco warehouse was also called kapnomagazo, since it was not only a storage space but also a place for processing tobacco [
46]. In the semi-basement of the building, the tobacco was dried (under humid conditions so that the leaves would not crumble), while on the upper floors, it was processed and packed into bundles. The company’s administration was also housed there on the third floor [
47].
According to the architect Manos Anagnostidis, who worked on the restoration of the building and its conversion into an office building, the industrial traits of the Parnassos warehouse serve as architectural memory, a material archive of commercial production and storage practices that shaped the city’s economic landscape [
48]. We should note that the preservation of the building as a historic monument affirms its symbolic value, but its potential to narrate the industrial past extends beyond preservation. In our research, elements of the building that were preserved in the restoration and conservation process dating from 1992, such as the building’s masonry, cornice lines, and fenestral proportions, become, based on our theoretical semiotics analysis, legible elements in a wider adaptive redesign strategy of the public space in front of the Technical Chamber building that makes historical processes visible in everyday space.
Our main design strategy to project the tobacco warehouse façade onto the square’s paving seeks to translate vertical architectural language dating from the industrial era into the new horizontal public ground. This intervention creates a visible continuity between building and plaza, reinforcing collective memory while providing cues for programming and movement. By echoing the building’s industrial geometry in paving patterns, seating layouts, and lighting, the new plaza could articulate zones for temporary markets, performances, and winter-proof seating, overcoming the seasonal lulls and dealing with residents’ and visitors’ expectations. Thus, the public space becomes a resilient, year-round civic threshold. The design proposal is aligned with industrial heritage preservation policies and tries to link the material resonance of the former tobacco warehouse with functional versatility: brick-like paving, modular benches, and discreet infrastructure for temporary stalls, which recall the industrial character of the neighborhood while supporting contemporary uses. In doing so, the project makes Komotini’s industrial past legible within its contemporary urban rhythms and supports a more continuous public life around a historically significant building.
