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 a side return extension?

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.

Planning and building rules in Warrington

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.

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

Does a side return need planning permission?

In England it can be permitted development if it is single storey, no higher than 4 m and no wider than half the original house. Conservation areas are the main exception.

Is a glazed roof too hot in summer?

Modern solar-control glass and a mix of glazed and solid roof keep it comfortable. We advise on the balance during design.

Can you visit a house in Warrington 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.
