This monolithic building stands like an erratic block?set at an oblique angle to its Baroque surroundings in Vienna’s museum district. No distinction is made between walls and roof. There are no windows to lend the building a sense of scale; and there are no obvious entrances. The mechanical services are integrated in the roof beneath a steel grid. The range of colours used for all the new structures and the pavings here is restricted to those of the existing surroundings: the pale tones of the rendered facades, the brick reds of the historical roofs and the anthracite grey of the asphalt paving. The Museum for Modern Art is clad in Eifel basalt.
