The location on the slope of Hubelstrasse poses a challenge and simultaneously provides a unique opportunity for intriguing apartment typologies that extend not only horizontally but also vertically. The sloping terrain offers the possibility to create not just conventional three-story apartments, but individual townhouses. Both parts of the house have their own garden and the opportunity for terraces and balconies with views. The local building regulations for a maximum of surface area, rather than volume, allows for the construction of double-height spaces - more volume for free. The situation on the slope reinforces this concept, as the terraced house typology can be «filled» with living space. The building becomes a compact cube on one hand, which can have a positive impact on costs, and on the other hand, it creates a spacious, light-filled living area that connects the apartments vertically.
