Paoli Hospital, part of Main Line Health, plans to build a new five-story patient tower on its campus in Willistown Township. County records say the work would remove two existing buildings and add a tower of about 152,400 square feet. The plan also includes a small morgue chiller, a parking garage and a parking lot. The campus covers about 47 acres.
Main Line Health's announcement describes about 108 new private inpatient rooms on three floors. Each room can be converted to intensive-care use. One floor would hold diagnostic testing. The project also includes a larger kitchen and dining area, new mechanical systems and emergency generators, and a rooftop helipad for trauma patients.
Main Line Health's governing board approved the project in June 2026. No township hearing or approval was found online.
What it could mean nearby
- Added parking (a garage and lots) suggests more daily trips to the campus, but no traffic study was found.
- A rooftop helipad could add occasional helicopter activity near the hospital. The sources do not describe flight frequency.
- More beds could mean more hospital jobs. One report puts current staffing at nearly 1,400 people.
- Two existing buildings would be demolished, and the site would gain more built area.
Where it stands
The hospital's own board approved the project in June 2026, and a county filing was recorded in August 2026. No township approval was found online. Next steps usually include township review of the land development plans, then permits before construction.
