Cape-Town-based studio Metropolis Design has completed the Spa House project in 2011. This contemporary home is located in Hout Bay, coastal suburb of Cape Town, South Africa.

Set on the mountainside on the urban edge of Hout Bay, overlooking the bay and harbour, surrounded by weathered sandstone formative. The primary design intention was to integrate the building with the powerful landscape and to derive its poetics from the qualities of its surroundings. The Spa House is separated from the principal residence by a berm, and is connected to it by foot paths.

Water constitutes the primary experience of the building. The floor planes are arranged to provide contrasting experiences of water, and the underwater spa with large viewing windows into the pool has a sense of stillness and mystery. The guest accommodation block hovers dramatically over the water and projects into space towards the mountain and sea. The dining area is submerged below water level, and pool decks are arranged as islands in a sea of water, connected by a bridge.
