FAQs

Garden Annexes questions answered

Do I need planning permission for a garden annexe?
Yes, usually. A garden annexe with kitchen, bathroom and sleeping accommodation is treated as ancillary residential use, which generally requires planning permission. Renting it out (Airbnb, long let) needs a Lawful Development Certificate or change-of-use approval.
How much does a garden annexe cost?
Garden annexes typically range from Β£35,000 for a basic 25mΒ² self-contained unit up to Β£120,000+ for larger two-bedroom builds with high-spec kitchen and bathroom. They're effectively small houses.
Are annexes subject to council tax?
Annexes used by family members are usually exempt or eligible for 50% discount under the 'family annexe' rules. Annexes let to non-family tenants are typically subject to full council tax β€” band depends on size and facilities.
Can elderly parents live in a garden annexe permanently?
Yes, and it's increasingly popular as part of multi-generational living. The annexe is connected to mains drainage, water and electrics; many have wheelchair-accessible thresholds, walk-in showers and step-free design. Planning officers are generally supportive of this use.
What about heating and energy bills?
We typically specify the annexe with its own electrical meter so usage is separately tracked. High-quality insulation and either electric heating or an air-source heat pump keeps annexe running costs manageable β€” typically Β£30-80/month in heating.
