Entry Description

This project gave us an opportunity to preserve a protected specimen of historical architecture in great need of restoration. We adapted the 350-year-old house to modern-day living requirements and transformed it into a zero-energy balance house without destroying its charm. All improvements are clearly visible and limited to exposed concrete, larch wood as well as black steel and glass. A photovoltaic system and solar panels collect solar energy. Surplus energy collected in summer is stored in the rock via the geothermal probe and can then be used as a climate-neutral energy source in winter.
