Percy Johnson-Marshall and Associates was founded, in 1962 , by Percy Johnson-Marshall as a Planning Consultancy, initially on the strength of his appointment as Planning Consultant to the University of Edinburgh for its Comprehensive Development Areas. The company was originally based in outbuildings at Johnson-Marshall's house, Bella Vista, Duddingston, Edinburgh. The company specialised in Urban Design and Regional Plans, with very few architectural designs before 1980 . Regional plans were produced for Porto, Portugal (1973-1975 ) and, in association with Sir Robert Hogg Matthew for Coleraine, Northern Ireland (1966-1968 ), and Islamabad (1961 ). Major redevelopment plans were also produced for Kilmarnock, Sunderland, Newcastle upon Tyne (1968-1971 ) and Salford (1961-1967 ). Between 1980 and his retirement in 1985 , Johnson-Marshall's input declined, as the company moved towards more conventional architectural work and urban improvements. During this time work began to appear under the name of Johnson-Marshall, Mackie and Hare, and later Percy Johnson-Marshall & Partners (PJMP), with Bruce Hare as principal architect.
