Single Storey Extensions in Newbury

How much does a single storey extension cost in Newbury?

A single storey extension in Newbury usually costs between £30,000 and £85,000. The final price depends on size, structure, access, drainage, roof design, specification, and how much work is needed to the existing house.

Single storey extensions are usually the simplest way to add ground-floor living space, but the roof, drainage, and opening into the house still need proper design. Costs move when foundations deepen, drains cross the footprint, rooflights or lanterns are added, or a wide opening needs heavier steelwork.

The quote should spell out foundations, drainage changes, brick and blockwork, roof finish, insulation, plastering, and Building Control inspections. For Newbury projects, a builder should explain planning route, groundworks assumptions, materials access, and how the programme fits the property.

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.

Cost should be read as a range until the house has been inspected and the scope is written down. A dependable price needs assumptions on structure, foundations, access, drainage, finish level, Building Control, and what is excluded.

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 single storey extension.

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.
