Hampshire Passivhaus is a self-build home on the south coast. It is an L-shaped detached dwelling, creating private courtyard spaces, on a tight brownfield site with multiple neighbours. Spruce CLT panels form the entire super structure, walls, floors and roof. The spruce panels give a tactile and harmonious quality to the living spaces and bedrooms. The prefabricated CLT superstructure was complete and watertight in just four days. European oak bespoke joinery is used to highlight interior features including the open tread staircase, recessed handrails, worktops and integrated shelves. Externally, the house is clad in Siberian larch rainscreen cladding, chosen for its straight grain, uniform texture and durability. The untreated larch ages over a short period of time to become silver, providing a maintenance free finish well suited to the coast.
