English architectural partnership. It was based in London and Saltash, Cornwall, and formed in 1959 by William Gough Howell (b London, 5 Feb 1922; d nr Leighton Buzzard, Beds, 29 Nov 1974), John Alexander Wentzel Killick (b 1924; d 13 Sept 1971), John Albert Partridge (b London, 26 Aug 1924) and joined in 1962 by Stanley Frederick Amis (b Egham, Surrey, 12 Jan 1924). The team from the London County Council’s Architects Department that designed the Roehampton housing estate (1950–61), London, HKPA belong to the post-war generation of architects with their roots firmly in the Modern Movement despite their penchant for non-literal historicism. They described themselves as pragmatists, dogmatic only about consistency of architectural form, detailing, materials and colour. The principle of separation and articulation can be seen behind all their work. In planning this may be expressed by the separation of a larger building into several distinct parts, an approach that stems both from the Modern Movement canon of the programme as generator of form and from A. W. N. Pugin’s principle of additive planning. Key examples of this discrete planning include St Anne’s College, Oxford (1960–79), Christ’s Hospital Arts Centre, Horsham, Sussex (1970–74), and their work for the Middlesex Polytechnic (1972–9). Spacious sites, phased construction and extendibility as well as scale, and circulation that is social and comprehensible typify the free planning of these schemes. However, separation and articulation have been achieved where such factors as a restricted site or a need for greater formality have called for a concentrated plan. Here the solution lies in spaces grouped to form a strongly centralized whole in a way that is reminiscent of Baroque planning. The earliest example is the University Centre, Cambridge (1963–7), while later ones include the Medway Magistrates Courthouse, Chatham, Kent (1972–9), and the Hall of Justice, Trinidad and Tobago (1978–85), its plan like a section through a honeycomb.
