The three-storey extension of the Porr headquarters is connected to the existing structure on the north side.
The corridor area can also be provided with daylight through the wedge-shaped opening of the two-row complex. Two staggered stairs in the void, located between the gallery-like corridors, also create spatial tension.
From the ground floor one can reach the somewhat lower lying event hall which the offices protrude above on two floors. An underground car park has been built underneath the new building and the visitors’ car park.
