New meeting point
Alongside the existing block, a new and dynamic building form is created. It resembles a bright tree with good conditions for growth as a green oasis in the city. The starting point is the classical and functional office building which has been optimised in terms of daylight, natural ventilation and building geometry to create excellent daylight conditions and views for the office spaces. The building is opened towards the surrounding city and integrates green courtyards via a branch-like structure at the outer perimeter, to let fresh air in and access the green spaces.

Four of these courtyards contain glazed atria, with open staircases connecting the ground floor with the upper office levels and a roof garden. These main staircases are situated inside the courtyards and acts as both escape route and wayfinding. At each floor, one arrives to a lounge area that provides access to specific office areas. This creates meeting points for breaks and exchange of knowledge and ideas in each office section, while the actual workspaces are situated in the less noisy and busy parts of each floor. The benefit from this is great flexibility in accordance to different users over time.

The main entrance and a public accessible canteen are accessed from the south at Niederkirchnerstrasse, as an elongation to the Abgeordnetenhaus. From the main entrance one moves through a large showroom to a conference centre in the middle of the building – designed as one open space that merges the conference centre with the functionality of the reception and foyer area. The conference centre also contains a library designed around a courtyard and which can be used as an alternative workspace to develop 'New Ways of Working'

The facade of the building is inspired by the varied density of tree crowns as a part of a multi-pronged low-tech sustainability strategy aiming at showing how to reduce the CO2 footprint within the future building and at the same time enhance the comfort for the building’s users.
