Begun in 1963 as Whitworth and Hall and attaining its present form in 1985, The Whitworth Co-Partnership has an established reputation for a range of architectural and building surveying projects. Boniface Associates was set up in 1993 and has an established reputation in general and building surveying. The practices merged on 1 January 2000. Both practices specialise in work to historic buildings, amongst other projects, and the merger produces what is probably the most experienced group of independent conservation specialists in East Anglia and the Northern Home Counties. WCP took over Andrew Andersons Practice in Norwich in 2004.
