House Extension Costs in London: What Shapes Your Quotation
Understand the scope, specification and site factors that shape a London house-extension quotation.
## What Shapes an Extension Quotation?
The design and size of the extension, structural work, access, ground conditions, glazing, finishes and changes to services can all affect the work involved. Planning, building-control, design and professional requirements also depend on the individual property and proposal.
## Compare Evidence, Scope and Quotations
When comparing builders, ask for current insurance documents, relevant recent references and examples of comparable work. Each quotation should set out the agreed scope, assumptions, exclusions, specification, payment stages and how client-requested variations or unforeseen additional work will be handled.
