Covering Banbury

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 goes into 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.

How is a wraparound extension approved in Banbury?

Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 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. Most need householder planning permission, which usually takes around eight weeks once validated.

What should Banbury homeowners check first?

The corner steel connection is the critical detail and is designed by a structural engineer.
Roof water from an L-shape needs careful falls and outlets.

How does the project run?

Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.

What people ask before starting

Can we keep part of the kitchen working?

Often, by sequencing the work so the old back wall comes out last. We agree a plan with you before starting.

Glazed roof or solid roof?

A mix usually works best: solid roof with rooflights over the kitchen and a glazed section over the dining area.

Who deals with the council for a project in Banbury?

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