Many garden room company websites base their Permitted Development guides on the rules outlined by England's Planning Portal. However, Scotland has slightly different regulations when it comes to building a garden room under Permitted Development.

This guide highlights the Permitted Development rules in Scotland for outbuildings, which is the term used by the UK’s planning portals to refer to garden room-type buildings.

Throughout the UK, Permitted Development rights allow homeowners to make small alterations or minor extensions to their homes without needing to submit a lengthy planning application.

Scotland is often overlooked in Permitted Development descriptions provided online, but it's important to recognise key legislative differences north of the border compared with England.

As in other parts of the UK, Permitted Development in Scotland does not apply to flats or maisonettes. If you live in one and plan to build a garden room, you will need to apply for planning permission.

As with all home improvement projects, the property owner is responsible for ensuring compliance with relevant planning regulations. Failure to do so may result in an order to remove some or all of the structure. It’s crucial that your garden room supplier understands the differences in regulations between Scotland and England.

This article is part of a series that explores the rules you need to consider when building a garden room.

Scotland’s Permitted Development Rules for Garden Rooms

The mygov.scot website outlines the current Permitted Development rules for garden rooms in Scotland:

  • It must be located at the rear of the house.
  • It must not be used as a separate dwelling.
  • The garden room, along with any other developments, must not occupy half or more of the ‘curtilage’ (the grounds behind your home).
  • The height must not exceed 4 metres at the highest point.
  • Any part within 1 metre of the boundary must be no higher than 2.5 metres.
  • The eaves (where the wall meets the roof) must not be higher than 3 metres.
  • If the land is within a conservation area or in the grounds of a listed building, the garden room must have a footprint of less than 4 square metres.

Rules for Decks and Verandas

It’s common to extend a garden room with a deck or veranda. The mygov.scot website also outlines the Permitted Development rules for decking:

  • It must be located at the rear of your house.
  • The floor level must not be higher than 0.5 metres above ground level.
  • The total height, including any attached structures or roof, must not exceed 2.5 metres above ground level.
  • If it’s within the grounds of a listed building or in a conservation area, the footprint must not exceed 4 square metres.

Check with Your Local Council Before Starting Work

Before building a garden room in Scotland, always check with your local council’s planning department. Even if you meet the Permitted Development requirements, you may still need to obtain additional permissions.

As with any home improvement project, the property owner is responsible for ensuring compliance with all relevant planning regulations. Non-compliance could result in an enforcement notice requiring you to remove part or all of the structure.

When choosing a garden room supplier, make sure they are aware of the differences between Scotland’s and England’s Permitted Development rules, so that the garden room can be properly designed and positioned.
