A. Hansen Gruppen

What A. Hansen Gruppen does

A. Hansen Gruppen AS is a Norwegian construction services company headquartered in Oslo that delivers building envelope solutions across roofing, facades, sheet metal work, carpentry, and solar cell installation. The company operates as a single integrated service provider (totalleverandør) for the outer shell of buildings, serving public-sector clients such as Oslo kommune alongside private property owners, developers, and enterprise construction firms including Veidekke, JM, NP Bygg, and J+I Bygg. Its technical capabilities include custom-fitted metal fabrication, green/blue sedum roofs, and specialist restoration work on heritage and protected buildings, supported by Miljøfyrtårn environmental certification and Åpenhetsloven transparency compliance.

The firm traces its origins to a sheet metal workshop founded in Oslo in 1970 and was formally consolidated into A. Hansen Gruppen in 2017 through the merger of several specialist companies. In 2023 it was acquired by Corteco AB, a Nordic group of entrepreneur-driven companies focused on sustainable renovation of building exteriors. A. Hansen retains operational autonomy in the Østlandet region while gaining access to Nordic-level resources and expertise.

Revenue is generated on a project basis through public tenders, private contracts, and direct project inquiries, with services delivered by an in-house workforce of skilled craftsmen and project managers. Marketing and customer acquisition occur primarily through the company website (ahansen.no), direct enterprise relationships, industry partner referrals, and demonstrated project delivery. The company does not publicly disclose pricing or revenue figures.

Core offering

A. Hansen Gruppen delivers integrated building envelope services (klimaskall) for commercial, public, and residential properties in Eastern Norway. The company installs, maintains, and renovates roofs, facades, sheet metal components, carpentry, and building-integrated solar panels, acting as a total supplier (totalleverandør) for the exterior of buildings. Services are delivered through project-based contracts covering new construction, rehabilitation, and energy-improving upgrades.

Product overview

A. Hansen Gruppen is a construction services company that operates as a single integrated offering rather than a platform-plus-modules architecture. The company provides five core service areas—Taktekking (roofing), Fasader (facades), Blikkenslager (sheet metal work), Tømrer (carpentry), and Solceller (solar cells)—that work together as a unified service portfolio for the building's outer shell (klimaskall). The services are designed to be comprehensive and holistic, with the company acting as a total supplier (totalleverandør) for all types of services for a building's exterior, with particular emphasis on sustainability and energy-improving measures. Since 2023, the company has been part of Corteco AB, a leading Nordic group specializing in sustainable renovation of building exteriors.
