Home Extension FAQs

Still unsure about something? Call us on 07534 362191 and we'll happily talk it through.

Does a home extension need planning permission?+

Many home extensions can go ahead under permitted development, depending on the size of the extension and your property. White Buffalo Bespoke advises you early, and if a full application is needed we handle it for you. See our home extension service.

How long does an extension take?+

A typical rear extension takes twelve to twenty weeks on site, depending on size, glazing and structural work. White Buffalo Bespoke gives you a clear programme before the build begins.

Can you live in the house during the build?+

Yes, most clients stay at home during an extension build. White Buffalo Bespoke stages the work, protects your home and keeps the site tidy so daily life can carry on as normally as possible.

Will my home be liveable during the build?+

In most cases, yes — we sequence the work to minimise disruption and keep dust and mess contained, though some projects require temporary access changes we’ll discuss upfront.

Do you offer a design-and-build service?+

Yes. White Buffalo Bespoke can manage your extension from initial concept through to final finish, or take on construction only if you already have approved plans.
