One speaks, with good reason, of a sense of space (Raumgefuehl) in architecture. But this sense of space is not a pure, abstract essence, not a sense of spatiality itself, since space is only conceivable as concrete space, within specific dimensions. A sense of space is closely connected with purposes. ... Architectonic imagination is, according to this conception of it, the ability to articulate space purposefully. It permits purposes to become space. It constructs forms according to purposes. Conversely, space and the sense of space can become more than impoverished purpose only when imagination impregnates them with purposefulness.
