The HSE has applied to build the residential unit in Portlaoise.
A decision on planning permission for a new 40-bed mental health facility is Laois is due at the end of the month (30th August).
The HSE has applied to build the residential unit at the site of St. Fintan's Hospital in Maryborough, Portlaoise.
The specialist facility, split into two 15-bed units and one acute 10-bed unit, would cater for older patients and include a number of dementia-specific beds.
Architects Wejchert say the 3,600 square metre building would be a replacement unit for some current facilities that do not meet standards at the existing St. Fintan's Hospital.
