Side return extensions in Nelson

Covering Nelson

Nelson is about 21 miles east of Preston. We also cover Burnley (3 miles to the south-west), Accrington and Rawtenstall.

Homes in the North West

Terraced housing is a defining feature of many North West towns, which brings party walls and narrow access into most projects, with more space to extend on suburban semis.

What is included in a side return extension in Nelson?

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.

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

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 Nelson homeowners check first?

Most side returns touch a shared boundary, so the Party Wall etc. Act 1996 usually applies in England and Wales.
Glazed roofs need careful detailing against the neighbour’s wall.
