The training complex for professional and academy players will sit alongside a 62,000 stadium – known as the Powerhouse – at the site in Bordesley Green.
In a statement the club said architects Populous were awarded the contract to bring "all the necessary facilities for the Men's, Women's and Academy teams onto a single site".
Head of infrastructure Nick Smith said the club's announcement was "another important step" in the delivery of the Sports Quarter.
"We are convinced that Populous will help us set new standards in sports infrastructure," he added.
"Together we can create a beacon of excellence that will inspire and support our local communities as well as setting the club up for success on the pitch."
Populous, which has its UK headquarters in London, has previously worked on projects at Tottenham Hotspur and Wembley stadiums.
Declan Sharkey, the firm's senior principal and global director, said: “Our aim is to combine our global expertise in elite training facility design with a bespoke approach, providing the club with an innovative, sustainable performance training environment and holistic environment for all of its teams and the staff who will use it.”
