The PolyCuboid Office Building by Tetsuya Matsumoto Golden Architecture, Building and Structure Design Award Winner 2020

The PolyCuboid Office Building

The PolyCuboid is the new headquarter building for TIA, a company that provides insurance services. The first floor was shaped by the limits of the site and the 700mm diameter water pipe that is crossing the site underground limiting foundation space. The metallic structure 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. The volumetric design is inspired by TIA’s Logo turning the building itself into an icon representing the company.
