    Questions

    Frequently Asked

    Do I need planning permission for an annexe?

    Most annexes fall under Permitted Development rights, meaning no planning application is required. However, the annexe must be used as ancillary accommodation to the main dwelling, not sold separately. We assess your specific situation during consultation and handle all compliance requirements.

    How long does an annexe take to build?

    From accepting the quote to handover, a typical annexe takes 3-4 weeks including groundworks and fit-out, depending on size and specification.

    What utilities does an annexe need?

    The annexe connects to your existing water supply, electricity, and drainage. We handle all connections and ensure compliance with Building Regulations. Running costs are typically added to your existing utility bills.

    Can I use the annexe for Airbnb or rentals?

    Many customers use their annexe for short-term lets or long-term rentals. However, planning permission is likely required for Airbnb or private rental use. It is up to clients to consult with their local council to confirm requirements for their area.

    What is included in the price?

    Our prices include the complete building with insulation, electrics, heating, UPVC windows/doors, internal plastering, flooring, kitchen, and bathroom. Groundworks, service connections, and site preparation are quoted separately based on your specific requirements.

    Do you offer finance options?

    Yes, we partner with finance providers to offer flexible payment options. Spread the cost over 1-10 years with competitive rates. We can discuss finance options during your consultation.
