Side return extensions in Neath

We take on side return extensions in Neath as a complete project: survey, drawings, planning or permitted development checks, building control and the construction itself.

Covering Neath

Neath is about 7 miles north-east of Swansea. We also cover Swansea (7 miles to the south-west), Ystalyfera and Maesteg.

Homes in West Glamorgan

Across Wales you find valley terraces, coastal towns, rural stone houses and newer estates, so access, slopes and local materials all feature in the design.

What goes into 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.

  • Party wall notices and surveyor liaison
  • Drainage and new gully positions
  • Underfloor heating ready screed if wanted

Planning and building rules in Neath

Welsh projects need planning clearance from the council under Welsh rules, building regulations approval under the Welsh approved documents, and party wall notices where the work affects a neighbour’s wall or foundations.

Wales has its own permitted development rules, set by the Welsh Government.

What should I think about before starting?

  • Access is often through the house, so we plan deliveries and protect floors.
  • Many terraces sit in conservation areas, where side extensions need planning permission.

How does the project run?

  1. Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
  2. Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
  3. Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
  4. Construction and completion. One site lead co-ordinates every trade through to the building control certificate.

Side return extensions: common questions

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.

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.
