Cost Calculator · Free

A realistic figure, before you're too far in to change course.

Move the controls and watch your budget update. It won't be to the penny — no honest estimate at this stage is — but it will be grounded in real UK build costs, and it's the number most people wish they'd had at the start.

01 Where in the UK?

Labour and material costs vary a lot by region. This sets the baseline.

02 How big?

Total internal floor area across all storeys. Not sure? A typical 3–4 bed detached home is around 140–200 m².

m²

150 m²  ·  ≈ 1,615 ft²

03 How will it be built?

The biggest single lever on cost — how much you take on yourself versus handing to a contractor.

04 What level of finish?

Kitchens, bathrooms, flooring, glazing, joinery — where taste meets budget.

05 How complex is the design?

Simple shapes are cheaper to build. Sloping sites, unusual forms and lots of glass add cost.

A guide only, based on typical UK costs. Excludes the plot itself, and any abnormal groundworks. New-build VAT is generally reclaimable. Your real figure depends on choices we'd work through together.

Why a range?

Because a self-build isn't a product with a price tag. Anyone quoting you a single exact number this early is guessing — I'd rather show you the honest spread.

What's not included

The plot, and any nasty surprises underground. Both matter enormously — and both are exactly the kind of thing I help you pin down early.

The next step

Turn this rough number into a real cost plan. That's where a short call with me earns its keep many times over.
