Costs, honestly
What an extension costs. A method you can check, a price you can hold us to.
Every price we give starts with a measured survey and a written specification, not a national average. Here is exactly how we price, so you can judge any builder's number, including ours.
Our pricing method
Measured survey first. Then a written specification. Then a fixed price against that specification, itemised so you can see what drives the number. Assumptions are stated in the quote, and anything discovered later is priced in writing before work continues.
The only number that matters
Ranges set expectations; they never buy a building. Your quote is fixed against its written scope, and our price promise means the number on it is the number you pay.

- The full scope and size of the project it covers
- The specification level, referenced to The Lifecycle Spec
- What is included and what is excluded: kitchens, made-to-order glazing, party wall costs and similar
- Every assumption stated, and anything discovered later priced in writing before work continues
- An itemised fixed price, so you can see what drives the number
Nothing we send you will ever be a countdown, a today-only discount or a pressure tactic.

Common questions
Because generic figures mislead. National averages ignore your site, your specification and this region's real costs, so a number that looks helpful can be a long way out. We price from a measured survey and a written specification instead, and the quote is fixed against that scope.
Book the free consultation. You get a fixed written quote against a written specification, and our price promise means the quoted price is the price you pay for the quoted scope.
Size and storeys, structural openings, glazing, kitchens and bathrooms, ground conditions, and how far the specification goes beyond the baseline. The quote itemises these so you can see what drives your number and what you could change.
