In many cases, no. Most garden offices, gyms and entertainment rooms can be installed under Permitted Development. Factors such as height, location, intended use and local restrictions can affect what is allowed. If you're unsure, our team can assess your project and advise on the most suitable route.

Yes. Many of our clients choose a garden annexe to provide additional living space for family members or guests. In some situations, an annexe can be designed under the Caravan Act, potentially avoiding a traditional planning application. We work closely with our planning partners at NAPC to assess each project and help make the process as simple and stress-free as possible.

Many garden buildings can be installed under Permitted Development without planning permission. Typically, the building should have an internal floor area below 30sqm and, if located within 2 metres of a boundary, a maximum height of 2.5 metres. If your requirements exceed these limits, don't worry — alternative solutions may still be available, and we'll be happy to guide you through them.
