Once planning permission has been obtained and prior to starting building works, the construction detail drawings are subject to Building Regulation approval by either the Local Authority Building Control Department or an approved Independent Inspector.
Building regulations are a set of requirements laid down by Central Government to ensure that building construction works are carried out to approved standards.
They cover a wide range of building works from major office, shop and residential developments to domestic works like extensions - loft conversions, garages.
