Do I need planning permission in Enfield Lock?
In England a single-storey extension to a bungalow follows the normal permitted development limits (3 m or 4 m, or 6 m and 8 m through prior approval). Adding a first floor always needs planning permission.
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).

Extensions in and around Enfield Lock
Our survey diary covers Enfield Lock, including EN3. The same team covers Ponders End (2 miles), Enfield (3 miles), Chingford (3 miles), Edmonton (3 miles), all within easy reach.
For homes towards Essex, Waltham Abbey is around 1 mile away. 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.
