Side return extensions in Bentley

Homeowners in Bentley 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 Bentley

Bentley sits 17 miles north-east of Sheffield, with Doncaster 1 miles to the south-east and Rotherham 11 miles to the south-west.

Homes in Yorkshire and the Humber

Yorkshire has a strong mix of stone terraces, red-brick semis and modern estates, plus conservation areas in many historic towns and villages.

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.

  • Party wall notices and surveyor liaison
  • Underfloor heating ready screed if wanted
  • Plastering and making good to the old house

Planning and building rules in Bentley

In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it 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.

How does the project run?

  1. Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
  2. We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
  3. Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
  4. Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.

What people ask before starting

Is a glazed roof too hot in summer?

About 10 to 14 weeks on site.
