Premium construction and renovation in Chiswick — extensions, loft and basement conversions, kitchens, bathrooms and full refurbishments, managed end to end from our Harefield base.
Hangard Construction works across Chiswick from our base in Harefield, a short run down through West London. We know the W4 streets well, from the Victorian and Edwardian terraces off the High Road to the listed Queen Anne Revival houses of Bedford Park and the riverside homes at Chiswick Mall. Loft conversions, house extensions and landscaping are the work we are most often called on for here, and we approach each one with respect for the period and the street it sits on.
Most projects in Chiswick involve the planning and conservation rules of the London Borough of Hounslow, and we handle that process for you from first drawings through to consent. We are used to the tighter controls that come with conservation areas and listed stock, and we detail the work so it reads as part of the house rather than an addition to it. The result is an extension, loft or garden that suits a period family home and holds its value on a sought-after street.

We tailor every project to the homes, ground and planning context of Chiswick — here's what that means in practice.
What sets us apart in Chiswick isn't a sales pitch — it's knowing the homes, the ground and the planning here, and building accordingly.
We prepare and run applications through the London Borough of Hounslow for Chiswick's conservation areas, including the listed Queen Anne Revival houses of Bedford Park.
We plan side-return and rear extensions around the outriggers, sash windows and slate roofs of W4's Victorian and Edwardian houses so the new work sits naturally.
We source red brick, hung tile and joinery to match Bedford Park's distinctive palette, so repairs and additions read as part of the original house.
We allow for clay shrink-swell near Chiswick's street trees and detail riverside plots at Chiswick Mall for tidal-Thames damp and flood risk.
