Extensions in and around Chingford
Our survey diary covers Chingford, including E4, E18, EN3, IG8, N9, N18. The same team covers Woodford Green (2 miles), Ponders End (2 miles), Edmonton (3 miles), Walthamstow (3 miles), all within easy reach.
For homes towards Essex, Waltham Abbey is around 4 miles away. London's housing is dominated by Victorian and Edwardian terraces, many with a rear outrigger and a side return, and 1930s semis in the outer boroughs. Conservation areas are common, so the planning check comes first.
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 over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).
Is a wraparound extension right for your house?
- 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
The corner is where wraparounds succeed or fail. We usually use a single steel goalpost or a corner post hidden in a pier, and set the glazing so the new room reads as one space rather than two boxes.
