Tomteboda was originally designed for entirely different operations than those later required. For many years after the postal service relocated, large parts of one of Stockholm’s most iconic landmarks were used for storage. One of the key challenges was therefore to adapt the property for future uses — but how, and for whom?
The ambition was high from the outset. Future requirements from both owners and tenants were not only to be met, but exceeded.
“When we gained a clearer understanding of our stakeholders, the journey began to transform Tomteboda from a 1980s industrial facility into a modern, tenant-adapted workplace of world-class standard,” says Nils Johansson, Project Manager at Co-Pilot.
A comprehensive analysis showed that even the largest investments would deliver strong returns. The work began with the replacement of all glazing and continued with new solutions for district heating and ventilation.
“This gave us a solid foundation for adapting the property to the needs of our tenants,” says Bengt Säberg, Property Manager at Newsec.
In practice, the entire interior of the building has been rebuilt — without any visible changes to the exterior. At the same time, the indoor environment has been significantly improved, creating optimal working conditions. The key has been continuity and a high level of trust between project management and contractors.
Many team members have been involved since 2018 and have developed a strong connection to the property. There is a clear sense of pride in the project and a mutual respect that is also reflected in efficiency and cost performance.
“Collaboration becomes both easier and more effective when everyone understands the common goal,” says Nils Johansson.
Tomteboda demonstrates that transformation does not always mean demolition and new construction. Often, it is about recognizing the value of what already exists — and having the courage to fully develop it. An approach that has proven highly successful, not least from a sustainability perspective.
In 2023, Tomteboda was named Project of the Year in the Renovation category — one of the most prestigious awards in the Swedish construction industry. The jury highlighted the project’s ability to build on an existing structure and transform it into a modern, sustainable, and future-proof environment with new functions and a long service life.
Tomteboda is owned by Blackstone and Areim
