Construction Quote Template
A structure built around how a real build actually gets priced: groundworks and the structural shell kept separate from finishing, materials flagged as a provisional sum rather than a guess dressed up as fixed, and stage payments tied to milestones instead of one lump sum.

Questions & answers
The Whitfield Family
Could you also quote for converting the loft while you're doing the extension?
StonePeak Construction
Yes — we'll have the site manager take a look while quoting the extension groundworks, free of charge, and send a separate loft conversion estimate alongside this one.

Why this structure
Construction quotes tend to get disputed at the end, not the start — because materials priced as a guess get presented as if they were fixed. This structure keeps the groundworks and structural shell (the things every build needs, priceable with real confidence once the design is fixed) separate from finishing and upgrades, which vary far more by customer taste. Materials that genuinely can't be fixed until work starts should be flagged as a provisional sum rather than folded silently into one number.
Commonly forgotten
- • Planning permission or building control application fees
- • Party wall agreement costs where work is near a boundary
- • What happens if unforeseen ground conditions are found once digging starts
- • A retention percentage held back until snagging is signed off
Terms to get right
Set out stage payments tied to completion milestones (foundations, weathertight, second fix, completion) rather than a single lump sum, and state any retention percentage held back until snagging is signed off.
FAQ
What's a provisional sum and when should I use one?
It's an allowance for costs that genuinely can't be fixed until work starts — use it for materials, not for labour or a structural stage you've already scoped, or the whole quote starts to read like a guess.
Should I quote a fixed price or a day rate for a build like this?
A fixed price per defined stage is usually clearer for a residential customer budgeting against a mortgage or savings; a day rate suits genuinely open-ended or hard-to-scope work — be explicit about which one a given line item is.
What happens if something unexpected is found once digging starts?
State this upfront rather than leaving it implicit: unforeseen ground conditions or existing structural issues are priced as a variation once found, agreed with the customer before work continues, not absorbed silently or used to justify an undiscussed final-invoice jump.
