In the geometric center of the GIZ Campus and the surrounding buildings, a permeable, public, individually customizable campus square stretches between the path alongside the railway and Ludwig-Erhard-Straße. Here the employees of the GIZ campus and the surrounding residents can come together for events, to play, to exhibitions and markets, to work and discuss together or to meet in the guest garden.
The existing trees combine with the new trees in the outdoor area and the trees in the high ground floor areas and inner courtyards of the building to form a loose grove of trees.
The new main building will be networked with a flying roof element from the new building to the current GIZ main building. This connection is resource-saving and requires no renovation work. The start and end point of the network is the central communication and access hall of the new building. Behind the security gate in the entrance area there is an open lobby situation that connects the restaurant and the communication center. Generous communication stairs vertically connect all office areas in this hall.
Based on the specified different room and area modules made up of work and lounge areas, the standard floor plan shows 8 home bases for 30 people each. The middle zone was provided with traffic routes on both sides, which creates more variation options in the module arrangement with the same space efficiency. The large support grid of 6x1.35 = 8.10m is precisely tailored to the module sizes and the expansion grid for selective renovation work.
All office workstations are arranged on the quieter external facades with openable windows and balcony and green zones in front.
In addition to its function as a cleaning walkway, the balcony zone in front of the office space can be used individually by employees in various ways. Together with the various vegetation areas scattered in front of the balconies, the image of a colorful, heterogeneous community is conveyed to the outside.
The building material wood determines the appearance of the facade and, together with the trees in the grove, forms a visible sign of sustainability through renewable raw materials that reduce the CO2 content of the atmosphere. The flexible adaptability of the building and thus the sustainability in terms of the easy implementation of future changes of use are obviously evident through the open framework structure.
The base of the building and the high, open ground floor area above it are planned to be constructed of reinforced concrete; The beams of the ceiling above the ground floor partially replace the central supports of the office wings and span the central rooms between the office wings without supports.
The supporting structure of the office floors OG1 to OG5 is planned as an economical and sustainable wood-concrete hybrid construction as a “framework” made up of supports and ceiling elements with a consistent support grid.
For later changes in the space requirements of the building, the area occupied by the scaffolding can then grow or shrink without the building structure itself having to be changed.
