This is a two-family residence in the city center. The building is designed to create two separate yet interconnected dwellings so that each family can enjoy their privacy but also interact freely. The interior of the house is presided over by a tree in an inner courtyard.

The small wooden-floored inner courtyard is surrounded by two glass walls so the tree can be seen from the bedroom and the living room.
The spiral staircase connects the floors through the courtyard.
