Sweden's Riksbank has set out plans for an extensive renovation and restoration of its headquarters at Brunkebergstorg in Stockholm, with an initial overall cost estimate of SEK 3.3 billion including replacement premises. The project is intended to replace ageing building systems and adapt the premises to current requirements for security, working environment and functionality while preserving the building's cultural and historical values. The headquarters, inaugurated in 1976 and designed by architect Peter Celsing, has Stockholm City Museum's highest level of cultural heritage protection, known as a blue classification, which constrains how the work can be carried out. Planned upgrades cover technical systems that have reached the end of their lifespan, including ventilation, electricity, fire safety and backup power. The renovation will also require measures to maintain high security standards both during construction and in the completed building, with the work being carried out with a focus on sustainability and long-term management. The cost estimate is an early planning figure that will underpin future investment decisions and may be adjusted before a formal decision is taken. Work is planned to start after the summer of 2027 and is currently expected to last about four years, during which the Riksbank's operations will move to replacement premises on Klarabergsgatan and Sveavägen in Stockholm.
