This Townhouse is located in an urban structure in Vienna with four apartments. Each apartment extends about three floors with integrated atriums inside to gain natural light through all floors into bathrooms and stairwell. The street façade is more or less closed while the garden façade is opened to the garden, an existing little park with personal and common outdoor areas for the owners. There is no access from public areas, mostly private. Each apartment and the layout can be easily adapted for disabled persons and allows many changes through a longer living period.
