Foster + Partners chief executive Mouzhan Majidi has left the architecture firm following 27 years of service.

Majidi had been at the business since 1987 and was appointed chief executive 20 years later in 2007.

Foster + Partners said in a statement that the firm is removing the role of chief executive completely replacing it with that of a managing partner.  The firm is also keen to hire someone with management expertise rather than an architectural background.

“The managing partner, who will be recruited from outside the practice, will work alongside the current senior team,” Foster & Partners said. “This move reflects the successful growth and increasing diversity of skills and research groups that now comprise the practice. We will be searching for an individual with exceptional and proven abilities to help lead the practice through its next phase of evolution.”

Firm co-founder and senior partner Norman Foster launded Majidi’s work and added that the decision to change the firm’s corporate structure will serve as a boon in the long run.

“We believe that the creation of this new role of managing partner will help support the continued success of the practice. The appointment will allow our many talented architects, designers and engineers to focus on what they do best,” he said. “At the same time, we greatly appreciate the contribution that Mouzhan has made to our practice over the years.”
