This building for 'creative talents' lies in a former industrial area and has a harbourside setting Ð one of the cranes has been retained. While the character of many other buildings has been destroyed to create modern sophisticated offices, here the architects were determined to retain the strong industrial character of the site and provide a focal centre for the area. The building is in three parts: two 'bookends' (one by other architects), the Chipperfield one a muscular concrete box and the 'books', an office building with larger open plan floor plates. The top two floors provide offices for the co-architects. To comply with strict German thermal regulations, the internal walls and floor are all isolated from the external skin. The end building is conceived as a series of double height lofts with mezzanine floors providing workspaces and exhibition areas for sculptors and painters. The ground floor is occupied by a cafe overlooking a raised square.

'The three elements are modulated and related with extreme care and sophistication as a studied and precise composition of some of the great themes of 20th century architecture Ð from the fineness of Miesian order to the coarseness of Corbusian raw concrete. In the end we found the power of the building compelling and its literal but artful transposition of the massing of the older harbour buildings convincing as a way of making the new do justice to the historic city.' Jury

'We have produced a building that sets out to locate itself by taking inspiration from the massive materiality of the existing dockland warehouses. I believe that its physical presence maintains this memory whilst at the same time providing spaces of volumetric simplicity and enjoying the manipulation of daylight and views of the surrounding docklands.'
