Use of Digital Tools (Wikihouse System) in Multi-Local Social Housing

Abstract

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.

Toward Cost-Effective Timber Shell Structures through the Integration of Computational Design, Digital Fabrication, and Mechanical Integral ‘Half-Lap’ Joints

“…Locking parts were labeled with the codes of their main connectors and corresponding panels, ensuring efficient and accurate assembly on site (Figure 5). For the cutting process, we converted the 3D designs into 2D plans, reorganizing the design information to optimize material use using OpenNest (version 1.5.1), a tool for nesting shapes efficiently [35,36]. This adjustment allowed for efficient arrangement of parts based on their shape, size, and the laser cutter's working area limitations, which are 1300 × 900 mm.…”
