Swiss architectural firm Herzog & de Meuron designed this exposed concrete apartment building that maximizes space by eliminating interior corridors.
Located outside the city of Zurich in Switzerland, this eight-storey concrete building houses 32 apartments in total that were designed to be a spacious as possible. To eliminate the need for corridors inside the building, four spiraling corner staircases were built, granting access to each of the four apartments that make up every floor. Each apartment can also be accessed by an elevator that opens into the units' kitchens as well.
The cylindrical staircases draw attention to each corner of this simple concrete apartment building and complement the simple grid system of this design. Both the interior and exterior of the building also feature an exposed concrete theme, with certain surfaces and mistakes left unfinished for a rough and raw aesthetic feel throughout.
