A unique urban district in Stockholm

Close to New Karolinska Solna and the Karolinska Institute, we’re developing Hagastaden, a science district with a focus on health, where workplaces, research and housing meet culture and recreation. In 2030, when the new district is expected to be completed, Hagastaden will comprise roughly 50,000 new workplaces and 6,000 homes. With a focus on attractive workplaces, we at Castellum are contributing our know-how in health and wellness through our work with WELL-certified properties. We develop workplaces that help employees and companies to perform and feel well. Our largest project in Hagastaden is the Infinity project, which comprises 23,000 square metres of office space for the next generation.

Science Culture Health


The workplaces of the future

We live in a time of change when people’s and companies’ needs and circumstances are constantly evolving. Castellum strives to continuously grow and develop to meet the needs of future workplaces adapted to new work processes. People’s work environment has a huge impact on enjoyment, creativity and productivity. But how do we know if an office is optimised to meet the employees’ and company’s unique needs? How do we identify these needs?

Working with Castellum means having access to our knowledge, drive and strength. Our ambitious goal to become an industry leader in digitisation has led us to launch a number of services to our customers that make daily life easier. As a long-term player and urban developer, it is natural for us to contribute to sustainable societal development.

Integrated sustainability all the way

In Hagastaden, we’re focusing strongly on creating a sustainable lifestyle for the people who will work and live in our properties by integrating sustainability fully into our operations. This means, for example, constructing resource-efficient buildings that meet high environmental standards. But above all, it means creating workplaces that people look forward to going to. We put people’s needs and wellness at the centre, for example by working with WELL certification.

WELL is an international building standard that focuses on health and wellness through seven concepts: air, water, nourishment, light, movement, climate and mental well-being. Castellum has knowledge and experience from many types of projects, as well as a large network of qualified partners. We offer support in creating a healthier workplace.
