The PolyCuboid

Best Constructed Public Building or Facility

About the project
The PolyCuboid is the new headquarter building for TIA, a company that provides insurance services.
The volume is composed by an interlace of three cuboid shapes creating intersections, voids, and space units. The cuboids superposition allows a richer space syntax including interior and exterior terraces, an atrium, several seating spaces, and a clear yet richer functional distribution of spaces and connections. Bridges also connects the cuboids from inside allowing a dynamic overview of the different spaces.
The metallic structure of the building dissolves into the diverse blocs of the composition. The pillars and beams vanish from the space syntax, projecting the impression of an object, while also eliminating that of a building.
