Do I need building regulations approval for a garden room?
The most important factors are:
If you want to put up small detached buildings such as a garden shed, garden room or summerhouse in your garden, Building Regulations (except Part P for Electrical works) will not normally apply if the floor area of the building is less than 15 square metres INTERNAL and contains NO sleeping accommodation.
If the INTERNAL 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 contains NO sleeping accommodation, and is either at least one metre from any boundary, or it is constructed substantially of non-combustible materials. (*As a solution to this it is possible to coat the cedar cladding of your garden room with a non-combustible Intumescent paint for timber and wood, derivatives are available in Water and Solvent based forms with fire ratings of 30, 60 minutes.)
In many cases, these structures will be exempt from requiring approval under the Building Regulations if they meet certain exemption criteria.
Part A of the Regulations for structural integrity is fully complied with, ensuring that the building is constructed so that combined dead loads (weight of structural elements), imposed loads (snow, maintenance activities, etc) and wind loads are accounted for. Issues addressed cover elements such as the size and bearing of roof timbers relative to the unsupported roof span per guidance issued by NHBC and TRADA.
Part L (does not apply to buildings under 50m2 internal floor area per Regulation 21) takes account of the insulation qualities of walls, roof, floor, doors and windows, and new Building Regulations introduced in April 2014 impose stricter fabric U-Values for England and Wales of:
Part P In the case of Garden Buildings Part P applies and any work is notifiable to the Local Authority. Work can be self-certified by an Electrical Installer who is registered as a competent person using aBS7671 electrical installation certificate for every job they undertake, with a copy given to the householder. This is supplied by Modern Garden Rooms where we are contracted to do this work.
