The building has five floors with one apartment on each of them. The main space is reached directly from the outside by an elevator and an external staircase, which gives every unit a private character.

▼建筑向内的一侧开横窗，室外楼梯直接通往户内，horizontal windows on the inner facade of the building, outdoor stairs run directly into the main space
The balcony, its loadbearing structure and the different openings create the sensation of experiencing one corner of the building as its center – as the center of a seemingly infinite space. The horizontal window in the main space, being attached on the inside of the wall, gives to this wall the character of an outside facade, creating a close connection between inside and outside and private and public.
▼主要居住空间，面向内花园的横窗在私密和开放之间找到平衡，main living space, the horizontal window opens to the inner courtyard finds balance between open and private
▼室内采用清水混凝土，不加装饰，the interior is composed of fair-faced concrete without decoration
▼阳台中部设有承重结构，给人以在房间中的感觉，loading structure in the balcony gives people a feeling of being in the center of a room
The construction of the building is radically straightforward, using only common standard products.
