Premium construction and renovation in Pinner — extensions, loft and basement conversions, kitchens, bathrooms and full refurbishments, managed end to end from our Harefield base.
Hangard Construction works across Pinner from our base a short drive away in Harefield, close enough to be on site early and to keep a job moving day to day. We know the difference between the listed timber-framed buildings of the old High Street and the cavity-brick Metroland semis that ring it, and we build accordingly. Most of our work here is bathrooms, loft conversions and rear extensions on the interwar stock that fills the streets beyond the village core.
We handle the planning side directly with the London Borough of Harrow, including the conservation areas at Pinner Village, Pinner Green and Pinnerwood Park, and the Article 4 directions that apply on some protected streets. A loft or a side extension here often turns on getting that consent right, and we manage it from drawings through to building control. Whether it is a new family bathroom, a converted roof space or an extension over London Clay, we set the job out properly before any work begins.

We tailor every project to the homes, ground and planning context of Pinner — here's what that means in practice.
What sets us apart in Pinner isn't a sales pitch — it's knowing the homes, the ground and the planning here, and building accordingly.
Harrow sits on London Clay, so we design footings and extensions for shrink-swell movement around mature trees rather than treating subsidence as an afterthought.
We carry out sympathetic repairs and alterations in the Pinner Village, Pinner Green and Pinnerwood Park conservation areas, matching original brick, timber frame and clay tile.
We handle consent with the London Borough of Harrow directly, including the Article 4 directions that remove permitted development rights on some Pinner streets.
The 1923–39 semis around the old village are our core work, and we know how their roofs, bays and cavity-brick walls take a loft or rear extension.
