This concrete house in Switzerland by Basel studio on3 architekten has gabled end walls that appear folded along central vertical seams (+slideshow).
An exposed concrete staircase connects the three storeys of Wohnhaus Ginkgo and is suspended behind a balustrade of taught wires between the two upper floors.
A large dormer window increases the amount of inhabitable space on the top floor, which overlooks the corridor on the floor below.

The house is located in the center of Oberwil, in the north of Switzerland.
The neighbourhood is designed by older one family houses and small stores. Due to its geometry, the house offers an unconventional floor plan with comfort, flexibility and space to move.
As the rooms are linked and correspond to each other, they are ideal for family life with space for individual creativity.
The open kitchen and the living room, which are on the same level as the terrace in the garden, form one area.
A large glass facade is the only separation between the interior and the external space. The two upper floors offer private rooms, seperated by sliding doors.

The gallery in the attic gives a wonderful view over the roofs of Oberwil and completes the concept of the flexible and open floor plans. The centre of the house is a stair made of exposed concrete.
