Double Storey Extensions in Maidenhead

What does a double storey extension build involve in Maidenhead?

A double storey extension build in Maidenhead usually starts with a site visit, planning check, written quote, drawings or calculations where needed, then staged construction through Building Control inspections and final sign-off.

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.

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 Maidenhead homeowners, the quote should separate structural shell, glazing, kitchen/finish allowance, and any drainage or flood-related checks.

Maidenhead work often centres on family homes, open-plan layouts, riverside pockets, and higher expectations for finish quality. Many plots have decent access, but drainage, glazing size, and high-specification interiors can move the budget quickly.

Maidenhead sits under Royal Borough of Windsor & Maidenhead. The Royal Borough of Windsor & Maidenhead can require careful handling where previous extensions, flood considerations, or conservation edges apply.

A good build process has clear stages: survey, planning check, drawings or calculations where needed, quote, start date, inspections, and handover. The homeowner should know when decisions are needed, when inspections happen, how disruption is controlled, and what counts as completion.

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.
