Atrium Ljungberg AB is one of Sweden's largest listed property companies, operating as a real estate management and development firm. The company's business model centers on the long-term ownership, development, and management of mixed-use urban environments across Sweden's major growth markets: Stockholm, Uppsala, Gothenburg, and Malmö. Stockholm is its primary market, accounting for approximately 80% of its total property value. The company's portfolio is predominantly office- and retail-led, with office spaces making up about two-thirds of its properties, while retail accounts for roughly 20%. The remaining portfolio includes residential, cultural, and educational facilities. Atrium Ljungberg generates revenue primarily through rental income from its commercial tenants, alongside income from project and construction work through its wholly-owned building contractor subsidiary, TL Bygg. The company is known for its ambitious, sustainable urban development projects, notably Stockholm Wood City—planned as the world's largest wooden city—and the revitalization of the Slakthusområdet (Meatpacking District) and Slussen areas in Stockholm. By integrating offices, retail, and residential spaces, Atrium Ljungberg maintains a strong competitive position in the Swedish real estate market, benefiting from high occupancy rates and a robust project pipeline.
