Here in the middle of the mountains we have created a self-sufficient ecological house using the most modern technology available. Mas Campolier is an ancient farmhouse adapted to the most efficient energy-saving techniques. It is both energetically independent and sustainable. The electricity is generated by photo-voltaique panels. Hot water is produced by thermal panels. The central heating is produced by a sophisticated biomass burner. The water is pure and clean, pumped straight from a well directly underneath the house.
