This uncommon looking contemporary home was designed by German studio Architekten Martenson und Nagel Theissen and is located in Tübingen, Germany. Called “Just K“, the house has an original architecture, a total of five floors and walls covered in rubber. According to the project developers, “the client commissioned the design of a family home that would provide passively heated living space for two adults and four children. Use of energy efficient passive house technology, natural application of materials and prudent use of the resources at hand, make the building sustainable. The question is, what is “good” living space? What defines it and what does one really need? These issues guided us in our approach to the layout of the house, which has been efficiently designed to optimally deliver maximum use of space, functionality and flexibility.maginative overlapping of spatial areas and uses were designed to give the inhabitants a feeling of spaciousness, manifold atmospheres and various realms of possibility—despite minimised living area“. We absolutely love the creativity invested in this project, a delightful crib with such a well defined personality.
