Frequently Asked Questions

Do I need an architect before finding a builder?

For planning permission applications, architectural drawings are usually required. However, for permitted development extensions, many builders work with a trusted architectural technician.

What is the difference between permitted development and planning permission?

Permitted development allows certain extensions without a formal planning application — typically single-storey rear extensions under 4–6m, subject to conditions. Larger or more complex extensions need a full planning application.

How long does a house extension take to build?

A single-storey extension typically takes 3–5 months from groundworks to completion. A double-storey extension takes 5–8 months.

Should I move out during an extension?

For most rear extensions you can stay in the house. There will be dust, noise, and disruption, especially when the rear wall is opened up.
