If unusual buildings are your thing, then this sundial house in Strasbourg, France may well be your ideal home. The unique Heliodome was designed as a bio-climatic living space that keeps the building cool in the summer and warm in the winter. The giant three-dimensional sundial is positioned at a fixed angle so that it stays in the shade during the summer months (when the sun is high in the sky) and is in the sunshine all day during the winter months (when the sun is low in the sky). The interior is surprisingly spacious, housing 3 floors, while the giant sundial window ensures the maximum light enters the building.
