Transitlager Dreispitz

Double Program — The local plan allowed for the addition of three extra levels on top of the existing 4 story building. The added volume was too deep to create an efficient housing layout.

New Cores — BIG divided the new volume into five sections with centrally located access cores.

Rotation — Each section is rotated in order to improve facade area, allowing for plenty of daylight into all units, while retaining the efficiency of a point house typology.

Grid — The rotated volumes are matched to the existing column grid, creating an economical structural system.

Sun Orientation — The resulting volume allows for units that are all facing in more than one direction, and where no unit is directly north facing.

Sky Lights — In the openings are placed skylights, letting daylight into the deepest areas of the atelier floor.

Sky Gardens — The leftover areas become rooftop gardens with views over Dreispitz.
