The architecture firm behind Birmingham's Royal Conservatoire building has won a competition to design a new office block in the city.
Feilden Clegg Bradley Studios has been chosen for Three Chamberlain Square which will be developed next to Town Hall and contain around 160,000 sq ft of commercial office space.
It will be the fifth building to be constructed at the £700 million Paradise project with a planning application due to be lodged with the city council next year.
Keith Bradley, senior partner at Bath-based Feilden Clegg Bradley Studios, said: "Our approach to Three Chamberlain Square is centred around sustainability, wellbeing and place.
"In one of the first post-covid office buildings to be commissioned in the UK, we intend to raise the bar and bring a game-changing office building to the West Midlands.
"Our ambition is to make a working environment which is desirable and attractive while pushing the sustainability aspirations to deliver a net zero carbon building."
Three Chamberlain Square is part of phase two of the overall development along with office block One Centenary Way, currently under construction, and a new 250-bedroom hotel.
Phase one includes office buildings One and Two Chamberlain Square and a new public realm.
A planning application was also recently submitted for Octagon, a 49-storey apartment block with 346 units at the north of the site.
Paradise is being brought forward through a private-public joint venture with Birmingham City Council, private funding managed by Federated Hermes and Argent as development manager.
Rob Groves, regional director with Argent, added: "Huge congratulations to FCBStudios for the hard work they put into creating a winning design for our next building.
"Three Chamberlain Square is going to be an exciting and unique addition to the Paradise estate and we can't wait to bring forward more details on the proposals as we move into 2021.
"One of the themes in FCBStudios pitch was for an 'outside-inside' design that would be highly sustainable and this made the design stand out in what was a very high quality field."
