Within the heart of Pollokshields conservation area, this red sandstone villa sits within a large level garden. Our brief here was to add new leisure facilities including a ten-metre swimming pool and sauna. Unlike most domestic projects where we work with mature villas, this project did not involve reworking the existing building layout. Almost completely hidden from the front elevation, our design is set out from a large single birch tree within the enclosed back garden. A curved glass screen along the length of the new space provides transparent continuous connection to the garden. The use of materials and scale of the extension is in harmony with the existing villa.
