If your building is away from the house, takes up less than 50% of the garden and is smaller than 15sq m, or in some cases 30sq m, you’re unlikely to need planning permission or Building Regulations Approval. However, there are exceptions – such as if you intend to use the room for sleeping – so check online at www.planningportal.gov.uk, and consult your local council’s planning department.
Prices start from £439 for a Buckingham summerhouse (H213cm x W198cm x D205cm) from B&Q to around £22,600 for a bespoke design from InsideOut.
