On a soft natural slope in a residential area of Stockholm in Sweden, the folks from RB Arkitektur came out with this impressive design. Dubbed Villa UH1, the building is an eco-friendly example of how to go beyond the boundaries. It has a roof covered in green moss and uses geothermal energy – harnessed by a heat pump, to supply the under-floor heating system. Thing are just as good on the inside. With an inner courtyard for privacy, large windows, open space and amazing furniture, Villa UH1 is a beautiful dream home, perfect for a family.
