Castellum to build $170M office development in Stockholm

Real estate firm Castellum is planning to start construction on a prestigious $170 million (1.7 billion SEK) office development called Infinity in Stockholm’s emerging Hagastaden district in Q3 2025, with move-in targeted for September 2027.

The 20,000 sq m project will feature 12 floors above ground, two basement levels, and amenities like a restaurant, gym and conference facilities at street level. Infinity is targeting top environmental certifications like Miljöbyggnad Gold and NollCO2 for energy efficiency and climate neutrality.

Castellum already owns properties adjacent to Hagastaden and cites strong demand for new premium office space in the rapidly transforming area connecting Stockholm and Solna into an integrated neighborhood district.

The large-scale office construction represents a major investment by Castellum in Hagastaden’s future as one of Stockholm’s premier business hubs. Moving forward with the high-profile Infinity project signals confidence in the district’s continued growth and development.
