Chiswick is mostly Victorian and Edwardian terraces, built for families. Most are still used that way today. A few Georgian houses sit closer to the river.
A rear extension and a loft are the usual first move here. Gardens tend to be longer than in Chelsea or Kensington, which changes the design.
Chiswick falls within the London Borough of Hounslow, not one of the central boroughs. Conservation areas cover several of its older streets. Source: Hounslow Local Plan 2015-2030, read on 7 October 2026.
Chiswick pricing is open book, on our own rate card. A budget estimate usually lands within a week.

Extensions and lofts
A Chiswick plot usually runs deep, so a single-storey rear addition suits it.

Architecture
The brief here is almost always a family house staying one. Not a flat conversion.

Basements
Chiswick falls within the London Borough of Hounslow. A basement here is assessed against Hounslow’s own policy, not CD11.

Interior design
Storage and a working kitchen matter more here than a single showpiece room.

Construction
Scaffolding and skips share the street with school runs. We plan deliveries around that.
