When you build a building you need to follow the building code. The building code in Sweden contains mandatory provisions and general recommendations.
Boverket publishes the Swedish building code. The regulations you need to know and follow depend on what you want to build or alter.
On these pages you can find Boverket's building regulations, BBR, and Boverket's applications of the European construction standards (eurocodes), EKS, in English. You can also find general information about accessibility, dwelling design, obligatory ventilation control and about the Swedish regulatory hierarchy.
