Your local builder in Chalfont
Hangard Construction works across the Chalfonts, from the old village cores of Chalfont St Peter and St Giles to the substantial detached houses set along the Misbourne valley. We are based in Harefield, a short drive south, which keeps our teams close and our supervision regular rather than occasional. Most of what we do here is home renovation, extension and landscaping work, on houses where the finish has to match the standing of the street.
The Chalfonts sit on the edge of the Chilterns AONB and within the Green Belt, so what you can build is shaped by where you build it. We handle the planning side with Buckinghamshire Council, from pre-application advice through to listed building and conservation consent where the village setting requires it. That means a single point of contact who understands both the design you want and the constraints the valley and the green belt place on it.

Building in Chalfont
We tailor every project to the homes, ground and planning context of Chalfont. Here's what that means in practice.
The homes we work on here
- Listed and period cottages in the conservation cores of Chalfont St Peter and St Giles, built in timber frame, brick and flint under clay-tile roofs.
- Substantial detached Edwardian and interwar houses in cavity brick, set back along the valley and the surrounding lanes.
- Later detached commuter homes with room to extend, where the brief is usually more space and a better-quality interior.
- Houses near the village greens and Milton's Cottage in St Giles, where any external change has to read as part of the historic setting.
What Chalfont homeowners ask us to solve
- Flood and groundwater resilience on valley-floor plots, where the Misbourne chalk stream has caused documented flooding in both villages when flows return.
- Careful repair of solid-wall and timber-framed cottages, with damp and insulation retrofit done in a way the fabric can tolerate.
- Extensions, basements and full renovations on detached homes, planned to sit within AONB and Green Belt limits.
- Hard-water problems from the chalk aquifer, including limescale damage to boilers and heating systems.
Why Chalfont homeowners choose us
What sets us apart in Chalfont isn't a sales pitch. It's knowing the homes, the ground and the planning here, and building accordingly.
Built for the Misbourne valley
We plan valley-floor renovations and extensions around the risk of chalk-stream flooding and groundwater, with detailing that holds up when the Misbourne runs.
Conservation core experience
We repair and extend listed and period cottages in the St Peter and St Giles cores using brick, flint and timber methods the original fabric was built with.
We carry the planning
We take extension and basement schemes through Buckinghamshire Council, including the AONB, Green Belt and conservation consent that the Chalfonts so often demand.
Honest about hard water
We allow for the area's very hard chalk water when we fit kitchens, bathrooms and heating, protecting the systems from limescale from the day they go in.
