Do I need planning permission in Welling?
In England a porch is usually permitted development if its ground floor area is no more than 3 m² measured externally, no part is over 3 m high, and no part is within 2 m of a boundary next to a road.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
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.
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).

Included in a typical project
- Tiled, slate or flat roof
- Planning check against the porch limits
- Foundations and drainage for rainwater
- Front door, glazing and electrics
Proportion matters on a porch more than on any other extension, because it is at the front. We match the roof pitch and brick and keep the front door in proportion with the house windows.
Local to Welling
Our survey diary covers Welling, including DA6, DA7, DA15, DA16, SE2, SE18. Neighbouring towns we cover include Abbey Wood (2 miles), Plumstead (2 miles), Bexley (2 miles), Eltham (3 miles).
Just over the Kent border, Dartford is about 5 miles 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.
