FAQs

Do I need planning permission for a garden room?

In most cases, no — as long as your build meets a few straightforward conditions:

  • It must be single storey and cannot be built in front of your property
  • If positioned within 2 metres of a boundary, the total height cannot exceed 2.5 metres
  • It cannot take up more than 50% of your garden
  • It cannot be used for living in or as a base for your business

There are some exceptions worth being aware of. These permitted development rights vary significantly for listed buildings, conservation areas, and designated zones like Areas of Outstanding Natural Beauty. 

If you’re unsure, we’d always recommend checking with your local planning authority before you proceed — or simply ask us and we’ll help point you in the right direction.

Timelines vary depending on the type of build. Modular options can be configured in minutes, manufactured within weeks, and installed in just a few days. Bespoke projects typically take longer due to design and build complexity, but we’ll provide a clear schedule from the outset.
