Hammersborg torg 1-3
In preparation for their relocation to Construction City in 2024/5, OBOS appointed KJ-A to upgrade, remodel and extend their current premises at Hammersborg Torg 1-3, ready for re-use as flexible and forward-looking office space. From inception, emphasis has been placed on environmental and social sustainability.
As a result, a significant proportion of the existing building fabric will be retained, namely the two original tower blocks at each end of the plot together with their lower, three-story counterpart in the centre. In contrast, a new eight-storey volume will be inserted between the two tower blocks, enabling a continuous, uninterrupted internal circulation while maintaining a legible hierarchy between old and new. Large expanses of glazing together with an open-plan configuration at ground level will ensure physical and visual permeability, thereby enhancing the public realm.
