Covering Bow

Bow is about 5 miles east of London. We also cover Stratford (1 miles to the north-east), Canning Town and Leytonstone.

Homes in London

Terraced houses dominate many London neighbourhoods, so most projects involve shared walls, narrow access and a party wall process. Conservation areas are widespread, and some boroughs have their own mansard and basement guidance.

What is included in a side return extension in Bow?

Side returns are small in area but heavy in detail: party walls, a glazed roof, and steelwork to take out the original back wall. We design the roof for light and drainage, agree the party wall process early, and keep the work tidy because access is often through the house.

  • Party wall notices and surveyor liaison
  • Structural steel to remove the side wall
  • Glazed or solid roof with rooflights

Do you need permission for a side return extension in Bow?

Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 applies.

In England a single-storey rear extension can often go ahead under permitted development: up to 3 m deep on an attached house or 4 m on a detached one, no higher than 4 m, with eaves no higher than 3 m within 2 m of a boundary. Deeper extensions, up to 6 m or 8 m, need prior approval from the council first.

What should I think about before starting?

  • Glazed roofs need careful detailing against the neighbour’s wall.
  • Many terraces sit in conservation areas, where side extensions need planning permission.
