A3 Arkitektkontor AS was a Norwegian architecture firm based in Harstad, specializing in architectural design, project development, and zoning/regulatory planning. Their portfolio included a wide range of projects in Northern Norway and Svalbard, such as nursing homes, kindergartens, airports (Harstad-Narvik and Kirkenes), police stations, cultural centers, hospitals, churches, and educational facilities. As of November 1, 2020, the business operations were transferred to Norconsult AS, with all employees moving to Norconsult's Harstad office. The company was renamed to A3 pluss AS and continues to exist solely to handle warranty obligations for completed projects, but no longer performs any design or planning work.
