Side return extensions in Willenhall

Covering Willenhall

We work in Willenhall (WV13) and the places around it, including Wednesfield, Wolverhampton and Walsall.

Homes in the West Midlands

Red-brick terraces and inter-war semis make up much of the housing in the West Midlands, which suits rear extensions, dormer lofts and hip-to-gable conversions, with more modern estates on the edges of the towns.

What does a side return extension involve?

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.

What will a side return extension cost?

Typical ranges for side return extensions. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.

Side return extensions	Guide price incl. VAT

Good specification	£3,700 to £4,150 per m²
High specification	£4,150 to £4,550 per m²

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

English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.

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 can change the price or programme?

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

Side return extensions: common questions

How much does a side return extension cost?

Usually about £3,350 to £4,550 per square metre including VAT, which works out at around £35,000 to £55,000 for a typical side return before the kitchen.

Will I need a party wall agreement?

Most likely, because the new wall usually sits on or near the boundary. We serve the notices and work with your neighbour’s surveyor if one is appointed.

Can you visit a house in Willenhall to quote?

Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
