Covering Slough
Slough sits 17 miles east of Reading, with Windsor 2 miles to the south and Maidenhead 5 miles to the west.
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 wraparound extension?
Because it removes two external walls, a wraparound needs careful structural design and a good plan for the corner where the steels meet. We design, apply for any permissions, build and finish the shell, and can fit the kitchen as part of the same contract.
- Pitched, flat or glazed roof with rooflights
- Glazing, insulation, plastering and electrics
- Optional kitchen supply and installation
How much should I budget for a wraparound extension?
Indicative costs for wraparound extensions. London and the South East usually sit towards the top of each range.
| 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 |
Do you need permission for a wraparound extension in Slough?
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 should I think about before starting?
- Roof water from an L-shape needs careful falls and outlets.
- An open-plan space this size needs a heating plan, often underfloor heating.
From first call to completion
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- 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.
Your questions answered
Does a wraparound need planning permission?
Usually yes. In England it combines a side and rear extension, which takes it outside permitted development in most cases.
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.
