Do I need planning permission in Golders Green?
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.
The planning position for a specific Golders Green address depends on its history and any designations, which is why we check it at the first visit.
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).
Local to Golders Green
Across N2, N3, NW2, NW4, NW11, we can visit, measure and advise. The same team covers Cricklewood (2 miles), Kilburn (2 miles), Finchley (2 miles), Muswell Hill (3 miles), all within easy reach.
Borehamwood, in Hertfordshire, is roughly 6 miles from Golders Green and also on our list. Across London, terraced houses with narrow side returns and tight access are the norm, which shapes everything from party wall notices to how materials reach the back garden.
Is a porch extension right for your house?
- Busy hallways with no storage
- Homes wanting better kerb appeal
- Front doors that open straight into a living room
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.
