Three and four storey building complex, characterized by the use of prefabricated concrete panels and red window hinges. Mårbacka is a part of the Televerket complex erected between 1962 -1972.

The building was awarded with the Kasper Salin Prize in 1969. Used as an office building until 2016. Currently the place is being converted into 1-4 room apartments, scheduled for completion in 2024. The promise is to keep the historic façade.
