The Urban Tree house is a family project and is based on the initiative of the grandfather Hans-Joachim and his grandson Kolja, who ultimately implemented the project. Once more, it is conceived as an experiment and a research project for new construction and housing in tune with nature. It is intended to serve as an oasis and inspire friends and guests of the family, as well as students and those interested in architecture. We were very enthusiastic when the developer, Kolja Stegemann, approached us with the idea of implementing tree houses in the urban environment of Berlin. Tree houses are normally associated with a rural environment or natural surroundings.
