"Kölner Brett" is the name of a building, designed by Cologne architects b&k+ in 2000, that blends living and working in each of its single units. On the occasion of Archilab, an architectural exhibition held at Orleans in May 2001, b&k+ and Staubgold present a musical translation of the "Kölner Brett", composed by To Rococo Rot. The music of To Rococo Rot reflects the architectural grid (twelve equally sized modules giving structure and shape to the building as a whole) as well as the possible individual living and working conditions of the dweller, respectively.
