Retrofit in Kennington

Kennington is home ground — village-edge Oxford, with 1900s houses along the older lanes and post-war stock around them. At St Swithun’s House we delivered one of our largest projects: 267 m² of external wall insulation on a 1900s detached home, the roof extended on every elevation to oversail the new envelope, seventeen new windows and doors, a full annexe conversion and a whole-house ventilation design — all under one scaffold and one contract.

We have also completed retrofit works on Bagley Close and Woodcroft, so the chances are we have already worked on a house like yours, within a few streets of yours.

What we do in Kennington

Whole-house retrofit and every element within it: internal and external wall insulation in breathable materials, loft, roof and floor insulation, high-performance timber and slim-frame windows, airtightness and smart ventilation, rewiring and heating — with heat pumps and solar designed and coordinated by us and installed with our managed certified partners. Fabric first, always: we cut the heat your house loses before changing how it is heated. See the full range of services.

Local, not just willing to travel

We are an Oxford construction firm. Our projects sit on streets across the county, our crew is local, and our survey visits are a short drive, not a scheduling event. When we quote for work in Kennington, the sequencing, scaffold and site logistics are planned by people who know the roads, the stock and the local planning context.
