— Common questions

Frequently asked about extensions & alterations.

  • Do I need planning permission?

    Many extensions fall under permitted development, but we'll advise during the initial consultation and submit applications where needed.

  • How long does an extension take?

    A typical single-storey rear extension takes 10–16 weeks; larger and double-storey works longer. We confirm a programme up front.

  • Can you work with my architect?

    Absolutely — we work both on a design-and-build basis and with existing architectural drawings.
