Wraparound extensions in Oxford

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

Covering Oxford

We work in Oxford (OX1) and the places around it, including Abingdon, Didcot and Witney.

Homes in the South East

Many South East homes are inter-war or post-war semis and detached houses with room for rear and side extensions, while historic town centres and villages bring conservation area and listed building controls.

What is a wraparound extension?

A wraparound extension combines a side return and a rear extension into one L-shaped build, giving the biggest possible ground-floor space on terraced and semi-detached houses. It usually creates a large open-plan kitchen, dining and living area across the back of the house.

  • Design, planning drawings and structural calculations
  • Party wall process with both neighbours if needed
  • Pitched, flat or glazed roof with rooflights

How much does a wraparound extension cost in Oxford?

Use these ranges to budget for wraparound extensions; the survey turns them into a fixed price for the agreed specification.

Wraparound extensionsGuide price incl. VAT
Standard specification£3,400 to £3,800 per m²
Good specification£3,800 to £4,250 per m²
High specification£4,250 to £4,700 per m²

How is a wraparound extension approved in Oxford?

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 wraparound extension is treated as one extension, and because it covers both the side and the rear it does not normally fit within permitted development.

What can change the price or programme?

  • The corner steel connection is the critical detail and is designed by a structural engineer.
  • Both neighbours may need party wall notices.

What are the steps?

  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. Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
