The Design of the Snowdon Aviary and the Nature of Collaboration

Although architects collaborate with engineers in the design of buildings, the contribution of the latter is seldom known to historians. This paper examines the design of the Snowdon Aviary at London Zoo, which is typically attributed to Lord Snowdon and Cedric Price. However, the vast majority of surviving design sketches are in the hand of Frank Newby, the structural engineer. Apart from giving clues about the way in which the design developed, these sketches leave the strong impression that Newby was taking the lead in proposing specific forms that the structure might take, because he alone was aware of the structural possibilities. The sketches raise the question: how common was this dynamic? Examples of Newby's contribution to other projects are suggested.
