Covering Accrington
Accrington is about 14 miles east of Preston. We also cover Rawtenstall (5 miles to the south-east), Blackburn and Darwen.
Homes in the North West
The North West has long rows of Victorian terraced houses in its towns and cities, alongside inter-war semis and post-war estates, so rear extensions, dormer lofts and kitchen extensions are common projects.
What does a single-storey extension involve?
A single-storey extension adds one level of new floor space to the back or side of a house, usually to open up a kitchen, dining or family room. It is the most common way to gain space without moving, and many can be built without a planning application.
- Building control application and inspections
- Foundations, drainage and structural steel
- Brickwork, roof, glazing and insulation
How much should I budget for a single-storey extension?
Typical ranges for single-storey extensions. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.
| Single-storey extensions | Guide price incl. VAT |
|---|---|
| Standard specification | £2,600 to £3,000 per m² |
| Good specification | £3,000 to £3,500 per m² |
| High specification | £3,500 to £4,000 per m² |
What approvals does a single-storey extension need in England?
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 single-storey extension?
- Building on or near a shared boundary usually means serving a party wall notice in England and Wales.
- Large glazed areas need to meet energy rules, which can shape the size of doors and rooflights.
How does the project run?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
Questions about a single-storey extension in Accrington
Do you need to dig up the drains?
Sometimes. If a public sewer runs under the extension, the water company has to agree a build-over or a diversion. We check this at survey stage.
Will the brick match?
We source the closest available match for colour, size and texture and agree a sample panel with you before laying.
Who deals with the council for a project in Accrington?
We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
