GARDEN ROOM PLANNING PERMISSION

Do I need planning permission for a garden room?

For the majority of homes, installing a garden room does not require planning permission.

In the UK garden rooms are typically classed as outbuildings, meaning they fall under permitted development rights provided certain guidelines are followed.

These rules exist to ensure new structures sit appropriately within a garden and do not negatively impact neighbouring properties or the surrounding area. Our garden rooms are designed with these guidelines in mind.

Planning rules can vary depending on your property and local authority.

Planning permission is usually not required, as garden rooms typically fall under permitted development — provided they meet the following criteria:

  • is used for incidental purposes such as a home office, gym, studio or hobby space

  • is positioned behind the main front wall of the house

  • does not cover more than 50% of your garden, including other outbuildings

  • is not used as separate living accommodation

  • is no higher than 2.5m if positioned within 2 metres of a boundary – our garden rooms are 2.45m high, designed to sit comfortably within this limit.
