The Willowbrook Health Complex in Corby has offered a range of health services to the community since the 1950s.
At the moment it offers a one stop shop for patients.
This includes Corby Community Hospital , which has 22 rehabilitation beds, and the Corby Minor Injuries Unit, which provides access to NHS treatment for sprains, strains, cuts and burns
There is also an X-ray department; pathology and phlebotomy services and a minor operations department.
The new development will increase these services and also provide care previously only available at A&E.
