The roof of the existing building contains Reinforced Autoclaved Aerated Concrete which is being replaced in public buildings following safety fears.
RAAC is a lightweight form of concrete used in roof, floor, cladding and wall construction in the UK from the mid-1950s to the mid-1980s.
Midlands Partnership NHS Foundation Trust has submitted plans for the new development after being allocated £18.2m by NHS England as part of a national programme to remove RAAC from all NHS buildings.
Simon Butler, Managing Director Building Central at Tilbury Douglas said: “As a highly experienced healthcare construction contractor, we will work collaboratively with MPFT to deliver this new facility which will improve the experience of patients and staff.
“The new building will also feature sustainable energy sources and more efficient construction methods to meet net zero carbon targets.”
