The design director of multidisciplinary firm Arup Associates, James Burland, will leave the firm at the end of this year.

Burland, 45, will continue as an independent consultant to the practice after 1 January 2000.

Since becoming design director in 1992, Burland oversaw the growth of the firm from 50 to 120 people.

He said this week: "Arup Associates is too big for me now. I want to pursue my own design interests. I won't be competing."

Burland will remain involved in selected projects, including the £90m Manchester Commonwealth Stadium, further phases of a £20m, 600-bed building at Durham University, a mixed-use development at Bristol Harbourside, and two new office buildings at the 162 ha Stockley Park business park in Uxbridge.

  • The Duke of York opened the first £6.5m phase of the new Arup Associates-designed graduate college at Durham University on Wednesday. The first phase of the college, called Howlands Farm, includes eight new three-storey buildings.
