Architecture

the project

In the course of the transformation of the former Bonn government quarter to the UN location and the new building of the World Conference Center Bonn (WCCB), three former member apartment blocks are being rebuilt, reconstructed in accordance with the preservation of historic buildings and upgraded in terms of fire safety and energy efficiency. Two of the buildings will be converted into 'boarding houses' for visitors to the convention centre. The third building will house 20 modern office and meeting rooms. The underground car park under one of the apartment houses is being extensively reconstructed.

our work

As part of the conversion, the buildings - including minimized interference with the existing building structure - are comprehensively refurbished and interpreted in a contemporary manner. These include the fire protection of the buildings including the underground car park, the energetic upgrading of the facades and flat roofs as well as barrier-free development of the entire building complex. The protected facades receive a - according to the historical model, executed as Kellenputz - thermal insulation plaster. Balconies and balcony railings characterize the facades as design elements. The railings are reconstructed and renewed. The ailing condition of the balconies necessitates extensive refurbishment of the concrete.

The 46 apartments will be renovated and designed according to contemporary living standards - some of which are barrier-free. The installation of new doors ensures the latest fire protection requirements and soundproofing improvements. All measures, such as the renewal of the surfaces, will be implemented in close consultation with the heritage authority.
The identity-creating floor covering made of split clinker brick in the entrance halls of the houses is retained. Defects are reconstructed consuming. Historical installations, such as the mailbox systems made of lockable wooden compartments, are reconstructed in detail or repaired. An information area will be created on the ground floor of the office building, which will be used by the Tourismus & Congress GmbH Bonn and will serve as a contact point for visitors to the former Bonn government quarter.
