Covering Crowthorne
Our coverage around Crowthorne (RG45) also includes Camberley (3 miles to the south-east) and Wokingham.
Homes in the South East
Housing across the South East mixes inter-war semis, post-war estates and older cottages in villages and market towns, so rear and side extensions, hip-to-gable lofts and garage conversions all come up regularly.
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.
- Party wall process with both neighbours if needed
- Steel frame or goalpost for the corner opening
- Glazing, insulation, plastering and electrics
How much does a wraparound extension cost in Crowthorne?
Use these ranges to budget for wraparound extensions; the survey turns them into a fixed price for the agreed specification.
| Wraparound extensions | Guide 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 |
What approvals does a wraparound extension need in England?
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.
What can change the price or programme?
- Roof water from an L-shape needs careful falls and outlets.
- An open-plan space this size needs a heating plan, often underfloor heating.
What are the steps?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- 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 Crowthorne?
We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
