We cover Stamford Hill and the postcode districts E5, E8, N4, N5, N15, N16. Nearby, we also take on projects in Harringay (1 mile), Highbury (2 miles), Tottenham (2 miles), Holloway (2 miles).
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.
What we take care of
- Front door, glazing and electrics
- Tiled, slate or flat roof
- Foundations and drainage for rainwater
- Brick, render or oak frame walls
- Planning check against the porch limits
- Design to suit the house style
Will the council need to approve it?
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.
Homes in conservation areas, national parks, National Landscapes (formerly AONBs), the Broads and World Heritage Sites have tighter rules, so we always check the property's status and planning history before design starts.
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.
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).

Design and approvals
Once the layout is agreed, we deal with the council: planning permission or written confirmation that none is needed, plus building control.

We confirm the build price in writing, based on the approved drawings and the finishes you have chosen.
