Garden Room FAQs

In England, many garden rooms used for purposes incidental to the house, such as an office, gym or studio, fall within permitted development and do not need planning permission, provided they meet the relevant size, height and location limits. For example, a building within 2 m of a boundary must be no more than 2.5 m high. Planning rules differ elsewhere in the UK. Flats, listed buildings, conservation areas and self-contained annexes have different rules. We give guidance at your free survey and can recommend an external planning consultant where an application is needed. [Read our planning guide]

For garden rooms up to 16 m², we guarantee installation within two weeks (10 working days) of the start of work on site, subject to the agreed specification, site access and weather. Typical working days on site:

• 14–16 m² garden room: 8–10 working days
• Up to 30 m²: 10–12 working days
• Annexe: 14–16 working days

Larger rooms and annexes are scheduled individually, and your quotation confirms the installation period for your project.
