This multi colored stairs is part of the Donmar Warehouse Theatre’s new rehearsal space. London firm Haworth Tompkins was asked to convert a 19th-century industrial space on Dryden Street, not far from the theatre, into a place that would provide additional offices, rehearsal areas and educational facilities. The Stirling Prize-winning practice collaborated with artist Antoni Malinowski on the project. Malinowski hand-painted the angular multicoloured wooden staircase, which the team envisioned as ‘the warm heart of the building’, in bold colours such as blue, purple and red. The rest of the interior has been kept raw to highlight the contrast between the daring new design and the building’s original brickwork, making the staircase the uncontested star of the show in the double-height space.
