It is the first house whose elevation has been made entirely of a plasticinsulating material -Thermopian. Usually, this material has been used only for roofing. Thermopian has good thermal, acoustic and insulating properties and it can have any required colour. We were intent on the house form to relate to the proportions of a Polish house but at the same time we wanted it to be simple and redefined. One distinctive leaning wall is a result of a compromise between a simple shape and the local law, which requires building in line with plot borders.
