The studios, in the Stratford East Bank development at the Olympic Park, will become home to the Radio 1 Live Lounge and BBC Proms.
It will have three music studios and two self-operated radio studios, an edit suite, and visualisation gallery. Studio 1 will fit an orchestra and an audience of up to 300 people, or a pop band with an audience of up to 800. There will be a variable acoustic system in Studio 2 that can handle a variety of uses, the BBC said.
The purpose-built studios will also be a hub for the BBC’s professional chamber choir, its symphony orchestra and chorus groups and rock and pop music sessions.
It will also host the BBC’s music education and outreach programmes, as well as housing one of the largest sheet music collections in the world.
Other music events, such as Radio 3 concerts and gigs from BBC pop music stations, are also being planned at the new venue.
The BBC first announced it would be moving its music studios from Maida Vale to the new creative quarter in east London in 2018.
BBC director-general Tim Davie, who visited the site on Wednesday, said he hopes the new studios will “allow us to reach audiences in new ways” and to “create ambitious music programming that audiences everywhere will enjoy”.
“We’ve been working with local schools on music education and careers sessions and my desire is that not only will big stars be broadcasting from our studios but that we’ll have inspired local talent to work with the BBC on their own doorstep.”
Many hope the move to east London will see more promotion of local talent.
Lyn Garner, London Legacy Development Corporation chief executive said it was “an amazing project with huge potential”.
She continued: “Stratford will see world class musicians with global appeal performing and recording for the BBC as part of these new inspiring and innovative studios.
“Local schools and communities are already benefiting from music education programmes as well career development, training and job opportunities.”
