1st Prize Winner of the Brazilian Institute of Architects, Pernambuco Chapter (IAB-PE) 2021 Awards, Geraldo Gomes Award for Technics, Technology and Innovation
Published as a full paper in the The SIGraDi 2021 Designing Possibilities, Ubiquitous Conference.

This academic initiative explores Augmented Reality (AR) via smartphones as a tool for constructing complex geometries, bypassing the need for Computer Numerical Control (CNC) or printed drawings. The Hyphae House, a 1:1 scale prototype, was erected on a university campus during the COVID-19 pandemic. Professors and students from a postgraduate course utilized locally sourced materials like concrete blocks and eco-friendly mortar.


Combining in-person and remote participation, the project demonstrated AR's effectiveness in design refinement, site adaptation, and construction. Accessible smartphone technology facilitated faster execution, approximately four times quicker than traditional methods, while promoting sustainability by eliminating paper waste and shoring pieces. An AR exhibition enhanced the prototype's informative and interactive aspects, showcasing its potential as a versatile construction tool.
