The primary objective of this study is to formulate a comprehensive digital and physical model, at a scaled level, for a social housing unit utilizing the open-source Wikihouse system. The construction industry is currently grappling with the dual challenges of a real estate crisis and climate change. In response to this scenario, the integration of industrialized methods in construction processes is advocated to enhance the overall quality of the end product, streamline construction timelines, and curtail production costs. The algorithm developed for this purpose leverages Rhino and Grasshopper programs, thereby optimizing material efficiency when compared to traditional individual pieces. Noteworthy among the features of the Wikihouse system is its remarkable versatility, allowing implementation in diverse locations. This flexibility stems from its efficient assembly characteristics, which liberate it from the constraints of rigid modular structures, contributing significantly to architectural design flexibility. The paramount finding of this research is the demonstrated efficiency of the proposed system, requiring 44% less time compared to conventional construction practices and exhibiting a commendable 29% reduction in costs. These outcomes position the Wikihouse-based approach as an appealing and competitive alternative within the real estate sector. Full article

The construction industry faces a significant challenge in addressing both the housing crisis and climate change. To mitigate this challenge, there has been a push toward the incorporation of industrialization in the construction process to improve product quality, reduce execution times, and lower production costs. However, it is also crucial to implement materials with sustainable characteristics to decrease the environmental impact of housing. In light of this, the present study analyzes the environmental and economic impacts through the development(design) of a modular construction system using materials with low environmental impact. Specifically, the structural components of the system are constructed using plywood boards, thermal insulation is provided by wheat straw, and the interior finish is made of clay plaster. The Skylark 250 model served as the chassis for the structure, with the wheat straw being applied through a blowing process and the clay plaster applied manually. Thermal transmittance, energy demand, environmental impact, and economic analysis were all evaluated for this solution. The study results yielded a modular housing solution with an energy demand of 55 (kWh/m²/year), which, when paired with photovoltaic panels, meets the Net Zero challenge. In terms of construction time, the proposed system requires 44% less time than traditional construction methods and is 29% less expensive economically, making it an attractive option for the housing market.

The housing crisis has received growing interest from academia, industry, and policymakers. Open construction systems have emerged as a promising solution to achieve long-term social, economic, and environmental sustainability. In this paper, extensive fieldwork was conducted to investigate a case of an open construction system, namely, the WikiHouse Den Bosch. The research framework builds on a combined view of two main concepts: “conviviality” and “openness”. The aim is to provide an in-depth understanding of the relationship between these two aspects and the literature regarding “Design Global Manufacture Local”. The analysis showed that conviviality and openness are complex and context-specific factors. The paper concludes by outlining the need for an “institutionalized conviviality” to open up new pathways for future practice to address sustainability issues. Full article
