Teknikhöjden is an empty building from the 1960s owned by Akademiska Hus and located in the northern part of the Albano campus in Stockholm. The building is covered by a demolition decision due to a long-ago decided zoning plan, and is now part of a dismantling and innovation project with the ambition of being able to build new from the old.
Teknikhöjden, with its 4,200 square meters, has a cast-in-place frame, interior walls in aerated concrete and concrete, and prefabricated concrete façade elements, and the ambition is to reuse up to 70 percent of the frame.
"Concrete and steel are two of the most resource- and energy-intensive materials to produce and often have a long lifespan left when dismantled. By making these resources available, we can significantly reduce the amount of waste, emissions and consumption of new resources from the construction and real estate industries," he said. says Oskar Söderberg, Project Manager at NCC Building Sweden.
The project is part of the innovation initiative Återhus 3.0 – to build houses out of houses, which aims to develop processes and standardised methods for dismantling and reuse. In order for the company to reach its climate goal of net zero throughout its operations by 2040 and secure campus areas that are developed and adapted for future needs, there needs to be more material available that does not use new natural resources.
"Teknikhöjden is a clear example of how we can save the earth's resources and reduce emissions through the reuse of heavy building components. An important part is also to develop new working methods and business models that are necessary to work with reuse on a large scale," says Linda Karlsson, project manager at Akademiska Hus and the company's responsible for the dismantling of Teknikhöjden.
The dismantling work started in early 2026 and is expected to continue until the summer.
About Återhus 3.0
"Återhus - to build house from house" is Sweden's largest research project on the reuse of heavy building components. The project has been ongoing in several stages over several years via Vinnova's call "challenge-driven innovation". Återhus 3.0 investigates the possibilities and methods for reusing and reusing materials from existing buildings into new ones construction, in order to be able to build houses out of houses. NCC and Akademiska Hus are two of the partners in the project, which is co-funded by Vinnova within the UDI3 research programme.
