Extensions to listed and period houses

An extension to a listed house is judged on how well it sits beside the original. Some match the old building closely, in the same stone and detail. Others are plainly modern and kept deliberately separate. Both can work. What matters is the quality of the design and the building.

Every extension to a listed building needs Listed Building Consent as well as planning permission. The architect leads the design and the application. We build it.

Matching the old building

At Maunsel House in Somerset, a Grade II* house now used for weddings and events, we built a commercial kitchen extension designed to be indistinguishable from the house. We sourced stone from the original disused quarry, built the walls nearly a metre thick and had new mullioned windows carved to match. The roof has fish-scale tiles and a weather vane on a lead and copper cupola.

At Okehampton in Devon, we built a Victorian-style orangery and gym onto an 1890 stone house, after first stitching its failing cavity walls back together with specialist ties.

Linking buildings

At Woolley Park, a Grade II* country house, we built a 1,000 sq ft orangery linking the main house to the annexe wing, forming a rear entrance hall and boot room. It has a lead roof, a basement, underfloor heating and a glazed screen with French windows onto the garden.

Larger additions

At Sussex House, we replaced a 1930s wing with a 2,000 sq ft extension holding a kitchen and living room with two bedrooms and two bathrooms above. The work was phased so the family could stay in the house.

At Poole Harbour, we added a steel and glass extension to an Arts and Crafts house, creating a lower ground floor and opening the kitchen onto the harbour.
