Single Storey Extensions in Slough

How much does a single storey extension cost in Slough?

A single storey extension in Slough 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 Slough homeowners, clear exclusions and a realistic programme matter because small access problems can quickly become extras.

Slough projects are often value-led improvements on busy residential streets, including semis, terraces, and practical family homes. Tighter parking, skip placement, and delivery access can affect labour time and should be discussed before the quote is treated as fixed.

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.

Slough sits under Slough Borough Council. Slough Borough Council checks can become more important where parking, overlooking, previous extensions, or dense street layouts are involved.

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.
