If I want to build a detached garage under 30 sq. m in floor area will building regulations apply?
No, the building will be exempt from the regulations but only providing it is: – under 30m2 in floor area; – single storey and does not contain any sleeping accommodation; and provided either: – it is built substantially of non-combustible material; or – when built it is no less than 1m from the boundary of the property.
