All you need to know about planning your perfect garden building. Whilst it may seem odd, it is not just major house renovations that are subject to planning permission.

Garden structures, such as sheds, upvc summerhouses and garages, are also eligible to the same stringent rules.

However, before you start to panic about the mountains of paperwork you may need to fill out, if your garden building fits within the following remits, you need not worry.

Location and Height

The need for planning permission for a shed focuses a great deal on the location and height of your new garden building.

If the building is to be placed less than 2.0m from your property’s boundaries, then the maximum height of the entire structure can be no more than 2.5m from ground level.

However, if you will be placing your new garden building more than 2.0m (1.0m in Scotland) from the boundary, then a single storey garden building can have an eave height of up to 2.5m, a dual-pitched roof up to 4.0m and a pent roof up to 3.0m.

Garden buildings planning permission would need to be sought if your structure exceeds any of these measurements.

Proposed Use for Garden Building

You will need to seek planning permission if your garden building is going to be used as a self-contained living space, such as a guest house, or if it has an antenna.

Size of the Structure

The new structure must not take up more than 50% of the area of land around the original house (meaning the house as it was first built).


Any garden buildings with additions such as balconies, verandas or raised platforms will need to seek planning permission.

When you are in the process of planning the installation of your garden structure, take time to decide what you want from your building and where the best location for it would be. This will then determine whether building permission is needed.

It is also important to take into account relevant building regulations when installing the structure, including electrical safety.

This requires that all electrical systems, whether in your home or garden, are certified by a qualified electrician to ensure they are safe.

Building regulation compliance is generally determined by the size of the structure, with any garden building over 30 square metres requiring full compliance with all applicable rules.
