The Practice was formed in February 1985. Donald Clark and John Farrell, the founding partners, both had extensive commercial and industrial experience in previous practices. The establishment and growth of the partnership has brought together a broad range of expertise in the planning, design and development of projects. There are now 8 partners and a staff of around 30 operating from offices in London and Leeds.

The Practice received its first civic trust commendation in 1987 for the design of offices in Francis Grove, Wimbledon and has subsequently won a number of local, regional and national design awards including the Green Gown Award in 2006, a York Design Award in 2008 and a Hull Civic Trust award and Leeds Architecture  Award in 2009.

In May 2005 the partnership converted to a Limited Liability Partnership with all existing partners, staff, clients and projects transferring seamlessly.
