Eight families use this apartment at four stories. The first and second floor are flat house, and the third and fourth floor are maisonette space.
These space with a unique shape links to all the maisonette parts by a different plan. However, the outside of the building keeps very simple form. Only a position and the size of the window tell the neighborhood about an internal characteristic. Also approach, parking lot and the outside storeroom are at the position clearing the snow and a legal limit reasonably.
