Fig. 5.19 Brick Country House Project, 1923-24. Ludwig Mies van der Rohe, architect. The plan of this projected build-
ing does not conform to the traditional parallel-wall arrangement seen above. Plans like this became possible only after
systems of horizontal structure which were capable of spanning in more than one direction (reinforced concrete slab,
steel space framework) had been developed.
