Building in Chiswick

Chiswick is a leafy west-London neighbourhood of Victorian and Edwardian terraces, mansion flats and the distinctive Queen Anne houses of the Bedford Park garden suburb. Much of it sits within conservation areas, so adding space is about respecting the street's character while opening up family living.

What we deliver in Chiswick.

Each Chiswick street has its own typical layout — Victorian terrace, Edwardian semi, 1930s detached. We adapt the recommendation to the house, the planning context and how you actually want to live.

01 · House extensions

Side-return and full-width rear extensions are the staple here — turning narrow Victorian kitchens into open-plan family space. We design them sympathetically and handle any conservation-area consent end-to-end.

02 · Loft conversions

Loft conversions add bedrooms and en-suites to Chiswick's terraces and semis without extending the footprint — ideal where the garden is precious or planning is sensitive.

03 · New builds

New-builds are uncommon in Chiswick's protected streets, but we take on backland and replacement-dwelling projects where the plot allows.
