Side return extensions in Gosforth

Homeowners in Gosforth can get side return extensions from one company: the design, the paperwork and the building work sit with us rather than with three separate firms.

Covering Gosforth

Gosforth is about 2 miles north of Newcastle upon Tyne. We also cover Newcastle upon Tyne (2 miles to the south), Gateshead and Wallsend.

Homes in the North East

The North East has terraced housing including Tyneside flats, inter-war semis and post-war estates, so loft conversions, rear extensions and layout changes are popular ways to add space.

What do you get with a side return extension?

A side return extension builds over the narrow passage that runs beside the back of many Victorian and Edwardian terraced houses, widening the kitchen or dining room by a metre or two. It is usually combined with a glazed or part-glazed roof so the deeper room still gets daylight.

  • Structural steel to remove the side wall
  • Drainage and new gully positions
  • Underfloor heating ready screed if wanted

How is a side return extension approved in Gosforth?

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.

What should I think about before starting?

  • Most side returns touch a shared boundary, so the Party Wall etc. Act 1996 usually applies in England and Wales.
  • Many terraces sit in conservation areas, where side extensions need planning permission.
