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).
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
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).
Working in Palmers Green
Across N11, N13, N14, N21, N22, we can visit, measure and advise. Nearby, we also take on projects in Wood Green (1 mile), Tottenham (2 miles), Friern Barnet (2 miles), Edmonton (2 miles).
Potters Bar, in Hertfordshire, is roughly 6 miles from Palmers Green 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.
