And among such false means largeness of scale in the dwelling-house was of course one of the easiest and most direct. All persons, however senseless or dull, could appreciate size: it required some exertion of intelligence to enter into the spirit of the quaint carving of the Gothic times, but none to perceive that one heap of stones was higher than another. And therefore, while in the execution and manner of work the Renaissance builders zealously vindicated for themselves the attribute of cold and superior learning, they appealed for such approbation as they needed from the multitude, to the lowest possible standard of taste; and while the older workman lavished his labor on the minute niche and narrow casement, on the doorways no higher than the head, and the contracted angles of the turreted chamber, the Renaissance builder spared such cost and toil in his detail, that he might spend it in bringing larger stones from a distance; and restricted himself to rustication and five orders, that he might load the ground with colossal piers, and raise an ambitious barrenness of architecture, as inanimate as it was gigantic, above the feasts and follies of the powerful or the rich.
Two-dimensional plans or sections can be seen with sketches and more diagrammatic marks all on the same piece of paper in what appears a confusing jumble.’ These sound like Gordon’s ‘wonder plots’. The architects also use their drawings as a means of thinking ‘aloud’, or ‘talking to themselves’, as Gordon put it. For example, Lawson reports the architect Richard MacCormac as saying, ‘I use drawing as a process of criticism and discovery’; and the engineer-architect Santiago Calatrava as saying, ‘To start with you see the thing in your mind and it doesn’t exist on paper and then you start making simple sketches and organizing things and then you start doing layer after layer.... it is very much a dialogue.’
The common elements in these similar descriptions are the use of drawing not only as a means of externalising cognitive images but also of actively ‘thinking by drawing’, and of responding, layer after layer and view after view, to the design as it emerges in the drawings. These observations also confirm Schön’s observation of designing as a ‘reflective conversation’ between the designer and the emerging design. It is the reliance on drawing, and the preference for the immediacy of the interaction and feedback that manual drawing gives, that makes the architects, like Gordon Murray, unenthusiastic about CAD as a conceptual design tool.
