K³ House by Hein-Troy Architekten

The K³ House was designed by Austrian architects Matthias Hein and Juri Troy of Hein-Troy Architekten for two young families to realize their dream of having their own homes on the top of their parents’ house.

To keep the garden area, the architects designed two overhanging wooden structures each for one of the clients reaching up to 5 meters and looking over the Constance Lake to the West. The concept was generated to get two completely different flats – a maisonette and a loft – each with private outdoor spaces and same living qualities so that the twins could easily choose their personal flat.

The vertical flat uses a split level to create a high living room with a kitchen on the next level, like the command bridge of a ship as the central element. The horizontal flat offers a number of rooms connected by floating facilities and multiple opportunities to live on a single level. The large loggia offers the best view and a protected exterior living room.

The parents stayed in there flat on the ground floor during the 12 months of construction. Their house was therefore completely isolated, got new windows and a wooden cover and became integrated in the new concept of a 3-families house with a lot of social advantages such as a recreational room with a garden terrace, space for their bicycles, a lot of storage in the basement and even two guestrooms that they can share all together.
