Premium construction and renovation in Chalfont — extensions, loft and basement conversions, kitchens, bathrooms and full refurbishments, managed end to end from our Harefield base.
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.

We tailor every project to the homes, ground and planning context of Chalfont — here's what that means in practice.
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.
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.
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 take extension and basement schemes through Buckinghamshire Council, including the AONB, Green Belt and conservation consent that the Chalfonts so often demand.
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.
