The silver medal in architecture from Sky Design Awards 2021.

The volumetric design is inspired by TIA’s logo turning into the building itself as an iconic building

Designed by KTX archiLAB, the project of the PolyCuboid is located in Himeji City, Japan. The PolyCuboid is intended for the new headquarter building for TIA, which provides insurance services.

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. The volumetric design is inspired by TIA's Logo turning the building itself into an icon representing the company.

The volume comprises three primary cuboid shapes creating intersections, voids, and space units. The cuboids' superposition across each other also allows a richer space syntax, including interior and exterior terraces, an atrium, several seating spaces, and precise yet more prosperous functional distribution of spaces and connections. Bridges also connect the cuboids from inside, allowing a dynamic overview of the different areas.

The first floor was shaped by the site's limits and a ø700mm water pipe crossing the site underground, limiting foundation space to half the land area. As a result, the middle volume stretching from 2nd to 3rd floor extends in cantilevers on both sides, allowing the building to gain precious square meters.

Functionally, a furnished reception and meeting space and 6 private desks and office space occupy the ground floor. The workspace continues to the next level with a conference room, CEO's room and second office space. This floor is separated into two areas by deferent floor levels, with the lower one dedicated to resting spaces, including a kitchen, a table terrace giving on the Atrium and a counter space. The third and fourth floors are devoted to recreation with various spaces such as a training room, dining space with a roof terrace and even a piano space on the Atrium. The staircase stretches from 1st to 4th level along the Atrium, although this last only reaches the third floor. However, the elevator block is the highest cuboid volume and was cladded in reflective black differently from the white cladding on all other volumes.
