This academic initiative focuses on the application of Augmented Reality (AR) via smartphones as a tool for the construction of complex geometries, without the use of Computer Numerical Control (CNC) or printed drawings. To test the current state of AR in the production of objects, the Hyphae House, a temporary prototype, in 1:1 scale, was built on a university campus by professors and students of a postgraduate course, accompanied by an exhibition in AR to expand its informative and interactive character.

 

The prototype was built during the COVID-19 pandemic, in a workshop with in-person and remote participants, including design refinement, site adaptation and construction, using locally produced concrete blocks and pre-ready ecological mortar as raw material. The experience had a positive result regarding the use of accessible smartphone technology as a complementary tool, at the construction site and in the computerization of construction.

 

The technology proved to be effective as a construction and visualization method, and led to the execution approximately four times faster than conventional processes, involving greater sustainability due to the absence of printed paper and shoring pieces.
