Planning consultant to the University of Edinburgh, Percy Johnson-Marshall was frequently asked to produce reports for specific projects, or sites, within the University Comprehensive Development Area (CDA), such as the High School Yards Site (1971) and the Empire Garage site (1977) Feasibility studies were also commissioned by the University from other architects, such as the Buccleuch Church site for which Robert Matthew, Johnson-Marshall & Partners produced unexecuted schemes in 1971 and 1973. Studies and reports carried out on behalf of other organisations for sites within the CDA were essential material for planning the CDA.
