Early Budget Review
Useful where an extension project needs early cost visibility before the pricing route is fully fixed.
Extension Cost Estimating
Extension cost estimating for contractors and projects that need clearer pricing before moving forward.
Millimetre Estimating Limited provides extension estimating support where projects need better cost visibility, measured quantities, and clearer pricing structure for extensions, alterations, and related residential building work.
What This Page Covers
Estimating support for extension projects where pricing clarity matters.
Extension work often carries more uncertainty than it first appears. Existing conditions, sequencing, design changes, and allowances can all affect pricing, which makes early cost clarity more important. This page is focused on estimating support for extension projects where that clearer structure is needed.
The service is suited to extension work in Glasgow, across Scotland, and the wider UK through a remote, document-led workflow using issued drawings and project information.
Where It Helps
Extension estimating is especially useful in these situations.
These are the common scenarios where clearer extension pricing helps reduce uncertainty before tendering or committing to a budget.
Tender Pricing
Support where a contractor needs better structure and take-off detail before pricing an extension return.
Scope Clarity
Helpful where existing conditions, alterations, and unknowns need more careful commercial review.
Who It Fits
Best suited to contractors pricing extension and alteration work.
- Contractors pricing domestic extension projects.
- Teams reviewing refurbishment and alteration work alongside extension scope.
- Projects needing measured quantities and clearer pricing build-ups.
- Enquiries where extension costs need more structure before a sum is committed.
Why It Matters
Extension work often needs more pricing care than standard new build.
Extensions can involve interface risk, hidden conditions, sequencing constraints, and variable existing fabric. Better estimating helps reduce weak assumptions and gives a firmer commercial base before work is priced or submitted.

Answers to the usual extension estimating questions.
Can extension estimating be provided from drawings sent online?
Yes. Drawings, schedules, and project information can be reviewed digitally as part of the remote estimating workflow.
Is this only for large extension projects?
No. The need for clearer pricing often matters just as much on smaller extension work where allowances and assumptions can quickly shift the cost.
Does this replace a calculator or rough budget figure?
No. This page is about professional estimating support where a project needs more dependable pricing information rather than a simple rule-of-thumb number.
