When considering the addition of a garden room in Glasgow, understanding the planning requirements is crucial. Typically, garden rooms or summer houses fall under permitted development rights, meaning you often do not need planning permission if the structure meets certain criteria. However, there are specific conditions to be aware of:
- Size and Height: The garden room should not cover more than 50% of the land around the original house. It must also be single-storey with a maximum eave height of 2.5 metres and a maximum overall height of 4 metres with a dual-pitched roof, or 3 metres for any other roof type.
- Location: The garden room must be positioned behind the front wall of your house and should not be placed forward of the principal elevation or any side elevation that faces a road.
- Use: The structure must be used for purposes ancillary to the main house and cannot serve as separate living accommodation.
