Building Regulations 2015​

Building work in new and altered buildings in Denmark

The Building Regulations contain the Danish rules for building work in new buildings, extensions, conversions and other rebuilding work, as well as changes in the use of buildings that are important in relation to the Danish Building Act or the Building Regulations, the demolition of buildings and alterations and other rebuilding work that may affect the consumption of energy in the building. The Building Regulations apply to building work carried out in the Danish market.

Their primary field of application is multi-storey buildings for residential purposes and all kinds of commercial, industrial and institutional buildings, including the categories listed in section 11 of the Danish Building Act, single-family houses for permanent residence, either as detached single-family houses or linked single-family houses, holiday homes in summer house areas, allotment sheds, campsite cabins and garages, outbuildings, and other secondary buildings.
