RBA designed this timber-clad Wiltshire pool house with natural swimming pool for private clients near Salisbury to replace two derelict existing outbuildings on their property. The site lies within an AONB, and so setting the new building and pool into the surrounding landscape to minimise its visual impact was integral to the design. The pool house has stone gables, built from local Chilmark stone, and a timber cladding that wraps over to also cover the roof. Slates underneath the timber provide waterproofing, and part of the timber roof structure remains uncovered to provide a brise soleil shaded terrace area. RBA also carefully considered the orientation of the building to maximise solar gain on the south elevation. The clients chose to install integrated solar panels there to provide renewable energy for the building, reducing its environmental impact. Internally, the clients use the main space of the pool house as a living area and games room. A striking floating log burner provides heating inside. The building also contains a changing room, w.c. and storage. The combined pond and swimming pool has wildlife friendly aquatic planting around the edges and relies on the sun and temperature to keep it warm. The contoured curved meadows adjacent to the pool are landscaped to encourage biodiversity and also protect the pool from prevailing winds.
