Arnøybygg provides planning and construction services for houses, cabins, commercial buildings or public projects. Arnøybygg is a northern Norwegian building contractor associated with timber-frame houses and leisure buildings.

The company has undertaken residential construction and local project work; the available public material does not clearly separate factory-prefabricated components from conventional site construction. Services are organised as site-specific contracts covering planning, applications, structural work, carpentry, trade coordination and construction.
