Covering Newbury
Alongside Newbury, we also cover Thatcham, Wantage (14 miles to the north) and Basingstoke.
Homes in the South East
Many South East homes are inter-war or post-war semis and detached houses with room for rear and side extensions, while historic town centres and villages bring conservation area and listed building controls.
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.
- Planning or lawful development certificate where needed
- Foundations, drainage and structural steel
- First-fix and second-fix electrics, plastering and making good

Planning and building rules in Newbury
In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.
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 change the price or programme?
- Drains under the footprint may need diverting or a build-over agreement with the water company.
- Kitchens and doors have long lead times, so we order them early.
What happens after I enquire?
- 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.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
What people ask before starting
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 Newbury?
We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
