Edward Hospital will begin work this summer on a $63.7 million expansion project that will add two floors and 60 beds to the west building of its Naperville campus.
The Illinois Health Facilities and Services Review Board approved the project in an 8-0 vote Tuesday.
Hospital officials said the expansion is necessary to meet growing patient demand.
"These new beds are needed to accommodate continued expected growth in our service area," President and CEO Pam Davis said in a written statement.
The project will add a third floor with 36 beds for orthopedic and spinal patients, along with a physical therapy gym, and a fourth floor with 24 intensive care unit beds and a storage area.
If all goes well, the work will be finished in late 2013, officials said.
The project will actually net Edward 48 beds, boosting its count from 309 to 357, because 12 beds elsewhere in the hospital will be removed.
Edward offers another 101 beds at neighboring Linden Oaks, its behavioral health hospital.
Earlier this month, Edward unveiled the state's first Ronald McDonald Family Room on its campus at 801 S. Washington St. It also plans this year to open a hybrid cardiovascular operating room and hyperbaric treatment rooms on its Naperville campus as well as finish one-story additions to existing inpatient wings at Linden Oaks.
Edward officials say they still hope to develop a hospital in Plainfield when the regulatory and economic climates improve.
