This stunning pyramid house in Iceland is sustainable and charming, I just can’t take my eyes off it! The house is kept warm by geothermal water. Pipes in the ground keep it warm and comfortable all year round. The electricity comes from a nearby geothermal power plant, hot water from a hot spring and cold water is natural spring water from a well. The house is a symmetrical design made up of two steep pyramids separated by the entrance hall and there is a huge hot tub outside. The use of light wood and white walls makes the house an open and airy space. One of the rooms is a loft with skylights – for viewing the northern lights. Up the stairs to the attic to see the sky through the triangular skylights. This house is perfect for enjoying the northern nature at its best.
