Branson Coates came up with initial designs for £15m expansion to Birmingham's Midlands Art Centre

Birmingham’s Midlands Arts Centre will open its doors to the public on 1 May following a two-year £15m refurbishment and expansion programme.

The scheme, which boasts more than half a million visitors a year, was developed over a period of more than ten years, with initial designs by Branson Coates Architects.

Local practice Chetwoods took the job to completion.
