Administration Building Allianz
After being rented out to a public agency, a remodeling and expansion was necessary for the administration building on Breite Straße, at the corner of Bastionstraße, a historically important building owned by the real estate company Allianz Immobilien GmbH. The various heights of the stories in the existing building made it difficult to use the building throughout. The historical facade was to be preserved as a significant part of the Düsseldorf inner city.
A large interior courtyard covered with glass as a “second access zone” into the building connected the various levels, for which a portion of the interior of the building was gutted. Additional stories of glass on the roof top for more office space fit in harmoniously and yet maintain their individuality in the structure of the existing facade.
A new floor plan allotment and a new underground parking garage contribute to the up-to-date use of the property. The familiar building does not relinquish its history, but continues to contribute to the design of the city.
