The redevelopment of the Comyn Ching triangle in Covent Garden, 1978-1985, was a residential and mixed-use scheme in an oddly-shaped plot, with a mix of sub-standard and single ownership buildings. The main objective of the project was to achieve a balanced development which converted and retained as many existing buildings as possible, and built only as much new development as would make the project commercially viable. The result was an island block, with a courtyard in the centre, which aimed to give the site as a whole a clear single identity. The scheme retained the listed buildings on the perimeter and refurbished them for mixed-use occupation. New corner towers, containing office and residential buildings, defined the edges of the development. The infill buildings at the centre of the site were replaced by the courtyard, in which two new office entrances were located.

Known building project dates are inclusive of the Farrell and Grimshaw Partnership company existence. However project material within the collection is dated within Farrells company operations.
