Local to Canning Town
We cover Canning Town and the postcode districts E3, E6, E13, E14, E15, E16. We also work in nearby West Ham (1 mile), Stratford (2 miles), Bow (2 miles), Stepney (3 miles).
Dartford, in Kent, is roughly 10 miles from Canning Town and also on our list. In London, space is at a premium and gardens are often short, so side returns, wraparounds and carefully planned rear extensions tend to make the most of every metre.

- Families who want kitchen, dining and living in one space
Will the council need to approve it?
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.
If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.
Applications are decided by the local planning authority (your district, borough or unitary council).

Wraparound extension questions answered
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Canning Town, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do you cover all of Canning Town?
Yes. We cover Canning Town and the surrounding parts of Greater London. Site visits are free and there is no obligation.
How long does a wraparound extension take to build in Canning Town?
On site, typically 14 to 20 weeks once approvals are in place. Before that, allow 8–16 weeks design and approvals.
Will I need to move a drain?
Often. Side returns frequently contain a manhole or a shared drain. Building near or over a public sewer needs the water company’s consent in England and Wales, which we arrange.
How much does a wraparound extension cost?
Our guide range is about £2,600 to £4,810 per m² including VAT. A 25 m² standard-spec wraparound typically lands around £74,500 to £94,500 in Canning Town before design and council fees.
