Double Storey Extensions in Newbury

Do I need planning permission for a double storey extension in Newbury?

You may need planning permission for a double storey extension in Newbury, but some projects can use permitted development. The answer depends on size, position, previous extensions, conservation status, and whether the work changes the roof or frontage.

Newbury sits under West Berkshire Council. West Berkshire Council checks can involve conservation areas, countryside-edge constraints, drainage, and the relationship with neighbouring plots.

Planning permission and Building Regulations are separate. Even if planning is simple, Building Control still needs the relevant structure, insulation, drainage, fire safety, ventilation, electrics, roof work, and final completion evidence for the specific double storey extension.

Newbury has a mixture of older homes, town properties, edge-of-town houses, and West Berkshire plots with more varied ground and access. Access can be easy on newer roads but tighter around older streets, with storage and delivery routes needing an early check.

Double storey extensions add space upstairs and downstairs, so the structure, roof tie-in, drainage, and neighbour impact need more careful coordination. Planning risk is higher because height, overlooking, loss of light, and roof massing matter more than on most single storey work.

The quote should include foundations sized for two floors, steels, floor structure, roof alterations, stairs or landing changes, and upstairs making good. For Newbury projects, a builder should explain planning route, groundworks assumptions, materials access, and how the programme fits the property.

Planning permission and Building Regulations are separate questions, so a project can be planning-light and still need full technical sign-off. Check previous extensions, roof/frontage changes, conservation status, boundaries, height, materials, and whether permitted development rights still apply.

Before agreeing the work, ask for a written scope that names inclusions, exclusions, payment stages, variation process, site protection, waste removal, and who manages the job day to day. That is the difference between a headline price and a buildable quote.
