Main Line Health is adding a 108-bed patient pavilion to its Paoli Hospital campus as part of push to expand its capacity in Chester and Montgomery Counties, the nonprofit health system announced Tuesday.
The building, expected to cost between $220 million and $240 million, is scheduled to open in early 2029. The project will expand Paoli’s capacity by more than 40%.

“While many communities face declining access to care, Main Line Health is moving forward with optimism, investing in this region’s future and reaffirming our commitment to exceptional care where people live and work,” Main Line CEO Ed Jimenez said in the announcement.
