Do I need ‘Planning Permission’ for a Garden Building…?
…In most cases you will not need planning permission to build a Composite Garden Building
Most Garden Buildings under 2.5 Metres high do not need ‘Planning Permission’
Garden Rooms are considered to be ‘Permitted Development’ and do NOT require Planning Permission if:
The building is to be placed less than 2.0m from the boundary of the property the maximum overall height should not exceed 2.5m from existing ground level
It has an internal floor area of less than 30m2
If you do comply with the above criteria, garden buildings up to an internal floor area of 30 square metres are generally exempt from planning and building regulations (Except when the structure is to be used for sleeping accommodation)
However you would need to apply for planning permission if:
Your Garden Building stands forward of the principal elevation of your house, fronting the highway?
Your Garden Building along with other buildings and additions, occupy more than half the area of land around the original house? (When it was first built or as it stood on 1st July 1948)
Your Garden Room is erected on land designated as a National Park, Area of Outstanding Natural Beauty, Conservation Area, World Heritage Site or similar
Your Garden Building be located within the curtilage of a listed building?
If you are concerned about planning, it is worth visiting your council with a rough layout of your garden, and a photograph of the Studio you want, because they will often just give you, ‘a letter of permitted development’.
