The construction task on this centrally located urban block combines renovation, monument preservation and new construction and thus creates a new coherent city block.
Planning 2006-2010 / Construction 2007-2010

The renovated and expanded Grünenhof combines nearly 900 workspaces, a conference centre and exclusive retail space. Transforming the listed shell of the building from the 1940s involved reconciling the ambitious aims of the project with the guidelines for monument protection. This was achieved using internal thermal insulation. The ‘Delphin’ partial replacement building completes the ensemble. With its meticulously staggered height and the pared-down choice of materials, it fits in discreetly between the two existing sections of the building, while still giving the city block a facelift.
