What can impact the cost of my extension?

Several factors can influence the cost of your extension, including its size and complexity, location and site access. Design choices, specifications, structural requirements, and planning fees can also have a significant impact on the overall budget.

The example costs reflect shell-only construction (including VAT). Additional elements—such as electrical work, windows and doors, plumbing, bathrooms, and any bespoke specification requirements—are not included and may increase the overall cost.
