Garden Office Installation FAQs

In most cases, garden offices fall under 'permitted development' rights and do not require planning permission, provided they meet criteria regarding height (2.5m near boundaries) and location. A Lawful Development Certificate (LDC) — currently £103 in most London boroughs — is strongly recommended to protect your investment. Always check with your local authority for listed buildings or conservation areas.
