The Spa House designed by Metropolis Design in Cape Town, South Africa, is set on the mountainside on the urban edge of Hout Bay overlooking the bay and harbor, and integrated with the beautiful landscape that surrounds it. This paradise home looks more like a luxury spa, water is an element with continuous presence in this space. The living areas were designed to allow a unique view of both the pool and the incredible surroundings. The Spa, located below the water level, has a direct view of the pool trough glass panels, providing a relaxing and mysterious effect. [source]
