Birmingham City Council held an open design competition to find a designer for the re-vamped Centenary Square in conjunction with the RIBA. Broadway Malyan was one of five practices to be shortlisted from a total of 185 entries.
The eventual winner was Graeme Massie Architects but Birmingham-based Broadway Malyan took the People's Choice award.
Board director James Rayner commented: "Winning the "People's Choice" accolade in this top quality, international design competition is an honour and means a great deal to us as a business with strong connections with Birmingham.
"It was a fantastic opportunity to be part of a process that will help shape Birmingham's future and we applaud Birmingham City Council and its sponsors for taking this open competition route."
He added: "We congratulate the winner and look forward to seeing Centenary Square evolve over the next few years."
Broadway Malyan is working on several other high profile schemes in the city including preparations for 'One Station Public Realm' - the newHS2/Moor Street/New Street station interchange space - and a new 'gateway' scheme for Snow Hill station. The practice is also working on a redesign and improvement scheme for the University of Coventry's Gosford Street Campus.
