The research aims to develop a framework to address needs to improve design to production workflow efficiency in the context of high-density urban environments through the application of advanced digital tools. The work primarily focuses on delivering the work through augmented reality (AR) driven assembly processes. Due to its modularity, affordability, sustainable building practices and accessibility, the research presents the self-build home as a design scheme to demonstrate such technologies. In the design proposal, an urban village rooftop intervention was proposed, adopting the open-source WikiHouse Skylark 250 modules as the design scheme for the self-build home. An AR immersive space was developed, where assembly sequence guidance was provided to aid potential self-builders to understand the building assembly process and safely, accurately and efficiently conduct on-site assemblies. The outcomes of the research provide lasting implications to the advancement of AR-assisted production workflows, and participates in ongoing urban village regeneration efforts which supports community revitalization, increases housing opportunities and maintains its social fabric.
