Do I need planning permission for a garden office in Devon?

A garden office can transform the way you live and work — but before you start building, it’s important to know where planning permission fits in.

The good news? In most cases, a garden office does not require full planning permission if it falls under your Permitted Development Rights. This typically applies when the structure:

• Is single storey

• Has a maximum eaves height of 2.5 metres (or 4 metres with a pitched roof)

• Sits behind the main house

• Doesn’t take up more than 50% of your garden

  
  

However, there are exceptions — particularly in conservation areas, Areas of Outstanding Natural Beauty, or if the building will be used as a separate residence.
