Do summerhouses or garden offices need building regulations approval?

If you plan to put up a small, detached building like a garden shed or summerhouse (classed as an outbuilding) in your garden, building regulations generally won’t apply if the building has a floor area under 15 square metres and does not include any sleeping accommodation.

For buildings with a floor area between 15 and 30 square metres, building regulations approval is usually not needed - as long as the building does not include sleeping accommodation and either:

  • it is at least one metre away from any boundary, or
  • it is built mainly from non-combustible materials.
