The spatial separation of living and working, in functional, modernist urban terms, is no longer in keeping with post-industrial society. The service industry, with its increasingly diverse forms of communication, work environments and personal economic needs, increased the possibility and demand for life-work spaces. A series of typological studies emerged from this context that look at the agency of modular organization in the formation of life-work environments. These studies have been ongoing since the 1990s, independent of any specific commission or context. The trope of combined work and living areas first appeared in Kölner Brett (1997-2000) with its flexible, lofty units and the Geisselstrasse project (1997-2000). In both cases, the typological exploration began with non-determinate spaces, while the projects that followed pushed the typologies to further limits.
