At our company, we offer all types of house extensions, including side extensions, rear extensions, kitchen extensions, and single and double-storey extensions.
The time required for a house extension project depends on multiple factors, such as complexity, type and size of the extension. On average, it can take from a few weeks to several months based on these factors.
Some house extensions in England can use permitted development rights, subject to limits and conditions. Some larger rear extensions need prior approval, and other proposals need planning permission. Check your proposal with your local planning authority. Building Regulations requirements are separate, so confirm the necessary approvals before work starts. See GOV.UK planning permission guidance.

Before comparing proposals, use our house extension quotation checklist to check the scope, exclusions and responsibilities in each quotation.
Gather the available drawings, property postcode and a list of rooms or finishes to retain. Record the kitchen scope, glazing choices, access for deliveries and any work needed in adjoining rooms. Compare quotations against the same information, including allowances, exclusions and who supplies each item. If you plan to stay at home, use our occupied-home renovation guide to discuss essential facilities and disruption. For a combined project, separate the new extension from the wider house renovation scope.
