Hounslow Borough covers Victorian and Edwardian terraces in Chiswick and Brentford alongside post-war semis in Hounslow, Heston and Feltham.
Planning in Hounslow
Standard PD rules apply for single-storey rear extensions. Prior Approval allows up to 8m (detached) or 6m (semi). Chiswick has multiple conservation areas — Bedford Park, Chiswick Village, Grove Park — where PD rights are restricted and planning permission is required.
Ground Conditions
Thames terrace gravel over London Clay is common across Hounslow. Clay soils require careful foundation design for extensions. RCB works with structural engineers as standard on all extension projects.
Costs
Single-storey: £38,000–£65,000. Side or double-storey: £70,000–£110,000. Second-fix materials client-supplied.
