Do I need planning permission in Hampton?
In England a wraparound extension is assessed as both a side and a rear extension, and the combination usually falls outside permitted development, so most need a householder planning application (£548 from 1 April 2026).
Homes in conservation areas, national parks, National Landscapes (formerly AONBs), the Broads and World Heritage Sites have tighter rules, so we always check the property's status and planning history before design starts.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
Applications are decided by the local planning authority (your district, borough or unitary council).
Who a wraparound extension suits
- Semi-detached houses with a side passage
- Families who want kitchen, dining and living in one space
- Terraced houses that want the largest ground floor possible
Local to Hampton
Site visits are available across Hampton (TW11, TW12). The same team covers Hanworth (2 miles), Feltham (3 miles), Surbiton (3 miles), Hounslow (4 miles), all within easy reach.
For homes towards Surrey, West Molesey is around 1 mile away. Across London, terraced houses with narrow side returns and tight access are the norm, which shapes everything from party wall notices to how materials reach the back garden.

Your questions about a wraparound extension in Hampton
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Hampton, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Will my neighbours in Hampton be involved?
If a planning application or prior approval is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.
How long does a wraparound extension take to build in Hampton?
On site, typically 14 to 20 weeks once approvals are in place. Before that, allow 8–16 weeks design and approvals.
Is a wraparound better than a side return alone?
It adds far more space, but costs more and needs planning permission more often. Our comparison guide sets the two side by side.
Do wraparound extensions need planning permission?
Usually, yes. In England the side element counts as a side extension and the rear element as a rear extension, and the combination normally falls outside permitted development. A householder application costs £548 in England from 1 April 2026.
