Our coverage around Abingdon (OX14) also includes Didcot (5 miles to the south) and Oxford.

Homes in the South East

The South East has a lot of 1930s and post-war semi-detached housing, well suited to rear extensions and hip-to-gable loft conversions, alongside period properties in conservation areas that need a more careful design.

What do you get with 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.

  • Glazed or solid roof with rooflights
  • Underfloor heating ready screed if wanted
  • Plastering and making good to the old house

Planning and building rules in Abingdon

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 affect a side return extension?

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

What happens after I enquire?

  1. Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
  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. We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.

Your questions answered

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.

Who deals with the council for a project in Abingdon?

We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
