Covering Bolton
Bolton sits 11 miles north-west of Manchester, with Farnworth 3 miles to the south-east and Westhoughton 4 miles to the south-west.
Homes in the North West
Across the North West, Victorian terraces, inter-war semis and modern estates all feature, and brick or stone matching is chosen to suit each street.
What does a single-storey extension involve?
We design the extension around how you use the house: where the light comes from, how the new room joins the old one, and what happens to the drains and the garden. The structure is built in brick or block to match the house, finished with a flat roof and lantern or a pitched roof, then insulated, plastered and handed back ready to decorate.
- Measured survey and design drawings
- Planning or lawful development certificate where needed
- First-fix and second-fix electrics, plastering and making good
How much should I budget for a single-storey extension?

| High specification | £3,500 to £4,000 per m² |
How is a single-storey extension approved in Bolton?
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. Deeper extensions, up to 6 m or 8 m, need prior approval from the council first.
What can change the price or programme?
- Drains under the footprint may need diverting or a build-over agreement with the water company.
- Building on or near a shared boundary usually means serving a party wall notice in England and Wales.
From first call to completion
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- 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.
Single-storey extensions: common questions
Can we stay in the house during the build?
Usually yes. We keep the existing house closed off from the works until the knock-through near the end, and agree a temporary kitchen set-up with you if the kitchen is affected.
Will the brick match?
We source the closest available match for colour, size and texture and agree a sample panel with you before laying.
