Homes we inspect in Hanwell
Around Hanwell Broadway and the streets towards Ealing, Hanwell has Victorian and Edwardian terraces, with interwar houses further out. The Brent valley runs along its western edge, crossed by Brunel's Wharncliffe Viaduct, and the Grand Union Canal climbs the Hanwell flight of locks to the south.
Loft conversions and rear extensions are the projects we design most often here, and we are regularly asked to look at cracking in houses near the valley.
Common structural issues in Hanwell
- Movement in houses close to the slopes down to the Brent valley.
- Seasonal movement on clay near mature trees.
- Cracks where extensions join the original house.
- Roof spread where loft conversions altered the roof timbers.
- Older drains leaking under part of a house.
Ground conditions
Hanwell has river terrace gravels and brickearth on the higher ground, with London Clay below and alluvium along the River Brent. Where a house sits close to the valley side, the slope and drainage need looking at as well as the soil.
We check the British Geological Survey records for every address we inspect, because ground conditions can change from one street to the next.

Common questions
Do you have an office in Hanwell?
No. Our office is at Gable House, 18–24 Turnham Green Terrace, Chiswick, W4 1QP, and our engineers travel to Hanwell for inspections and site visits.
Do I need calculations for a single-storey rear extension?
Usually, yes. Building Control will want calculations for the foundations, any steel beam where the back wall is opened up, and the roof. Even when the extension is permitted development, Building Regulations approval is still needed.
