Welcome to Castellum

In everything we do, we put people at the centre, and design the real estate to work for them.

Castellum is one of Sweden’s largest real estate companies. Castellum is also one of Sweden’s most prominent property-developers and one of the country’s largest real estate companies listed on the stock exchange – every day 250,000 people go to work in our buildings. Castellum maintains a local presence in 20 cities from Copenhagen in the south to Sundsvall up north, and we serve our customers at close range, backed by the resources of a major corporation. We manage 676 commercial properties for business and public services purposes, and we are driven by our passion for sustainability and innovation. All at low risk.
