A closer look at the wall build-up and window detail at Gullane House.
We try to keep our material palette simple and use sustainable materials wherever possible. For this extension, the wall build-up is timber throughout: a timber frame structure, wood fibre insulation and thermopine cladding from Russwood which will weather naturally to a silvery grey over time.
We took the time to carefully set out of the rainscreen timber cladding helps give the elevations rhythm and character.
The wood fibre insulation wraps around the outside of the structure, creating a particularly effective thermal envelope. The triple-glazed windows combine timber frames with aluminium cladding externally, providing warmth and natural materials inside, with durability and low maintenance outside.
Getting these details right at an early stage helps improve building performance, reduces embodied carbon and lower energy use. It's something we enjoy helping homeowners achieve as part of the design process.
