Single Storey Extensions in Slough

Do I need planning permission for a single storey extension in Slough?

You may need planning permission for a single storey extension in Slough, 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.

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.

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.

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.

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.
