Sauerbruch Hutton is an international studio for architecture, urban planning and design. Founded in London in 1989 by Louisa Hutton and Matthias Sauerbruch, it is now based in Berlin. From 1999 the two founders have been sharing their responsibility with Juan Lucas Young; since 2020 with 13 further partners. Drawing in Space is the first exhibition dedicated to Sauerbruch Huttons drawings that have been created over some thirty-five years. A wide array ranging from the founders individual student and early collaborative works executed in ink, charcoal, watercolour and, to digitally produced drawings and carried out in a further variety of graphic techniques by teams in the studio. This catalogue presents a visual cross section of the drawings - together with a sampling of their related projects - in a loose, associative sequence that unfolds independently of medium, technique or context of each particular work. This gives rise to a panoramic view of architectural themes as well as an insight into the processes of reflection that inform the creation of Sauerbruch Huttons architecture: drawing is an indispensable means for the discovery of form, colour and material in both real and imagined space. The catalogue documents not only the hanging of the works in the Tchoban Foundation, but also an interactive installation that was conceived especially for this exhibition: playfully extending the idea of the 2-dimensional drawing into 3-dimensional space, inviting visitors to step into the artwork itself. An essay by Kirsty Bell completes this tour dhorizon.
