If you want to put up small detached buildings such as a garden shed, cabin or a summerhouse in your garden, building regulations will not normally apply if the floor area of the building is less than 15 square metres.
If the floor area of the building is between 15 square metres and 30 square metres, you will not normally be required to apply for building regulations approval providing that the building is either at least one metre from any boundary or it is constructed of substantially non-combustible materials.
In both cases, building regulations do not apply ONLY if the building does not contain any sleeping accommodation.
