Constructing Ancillary Buildings

​

If you're considering adding a shed, garage, greenhouse, or other building to your property, known as 'ancillary buildings,' ensure compliance with planning regulations. Most ancillary buildings fall under 'permitted development,' exempting them from planning permission.

​

Permitted Development Criteria:

​

• Located at the back of the house

• Not intended for separate residential use

• Combined with other developments, does not exceed half the curtilage

• Height not exceeding 4 meters at its highest point

• Any part within a meter of the boundary not exceeding 2.5 meters in height

• Eaves height not exceeding 3 meters

• For properties in conservation areas or grounds of listed buildings, footprint less than 4 square meters

​

Always consult your council's planning department to confirm requirements. Even if meeting permitted development criteria, additional approvals may be necessary. For detailed guidelines on permitted development for ancillary buildings, refer to the Scottish Government's Guidance on Householder Permitted Development Rights publication, section 4.74. If your proposed building doesn't meet permitted development criteria, you must apply for planning permission.
