Corewell Health showed its plans for two major hospital campus expansions that will run the Michigan nonprofit system $1.7 billion.
“As our communities grow and patient needs become more complex, we are building the capacity, technology and care environments needed today for our patients and team members for many years to come,” President and CEO Tina Freese Decker said in the organization’s Thursday announcement.
The larger of the two projects is coming to Corewell Health Butterworth Hospital in Grand Rapids. The 780,000-square-foot, 11-story tower will include a new ED, 180 private patient rooms, 17 operating rooms and a hyperbaric chamber, Corewell said.
That project reflects a $1.34 billion investment and will the demolition of existing facilities, the system said. Notably, the organization will need to seek “various city approvals” to accommodate areas of building design such as the height.
“We’ve outgrown our current facility,” Josh Kooistra, D.O., president of Corewell Health West Michigan, said of the project in a statement that also highlighted the Buterrworth Hospital’s above-90% average patient census. “To be able to continue to deliver exceptional care as the only Level I trauma center in West Michigan, we need to expand access and modernize facilities.”
The other new tower comes with a $440 price tag for the organization and will be built at Corewell Health Beaumont Troy Hospital, which serves a “rapidly growing” community and is also “consistently” above 90% capacity.
The eight-story build will comprise 180 private rooms with “state-of-the-art technology,” a new waiting room for the hospital’s ED and help generally improve access to the rest of the hospital’s campus. Corewell’s announcement described a layout that will help patients and families having direct access from the hospital’s parking deck to the ED, creating “a more seamless arrival experience for one of Corewell Health’s busiest emergency departments with more than 106,000 visits per year.”
Both projects are scheduled to begin next summer and are targeting 2030 completions. Though subject to regulatory and municipal reviews, they already have backing from local leadership.
“The significant investment Corewell Health is making in our city to meet immediate and future increased patient demand will undoubtedly help provide people across West Michigan with greater access to modern, high-quality healthcare,” David LaGrand, Grand Rapids’ mayor, said in a statement included in Corewell’s announcement.
“The new hospital tower will create a better experience for patients and families and will support the future health needs of our community,” said Troy Mayor Ethan Baker in another included statement. “We welcome this significant commitment to Troy and look forward to the positive impact it will have for years to come.”
A 21-hospital nonprofit formed through the 2022 merger of Spectrum Health and Beaumont Health, Southfield, Michigan-based Corewell Health is the state’s largest health system. It employs more than 60,000 people and hosts over 5,000 licensed beds, more than 300 ambulatory and outpatient locations and a health plan with over 1.4 million members.
Across 2025, the system grew its operating revenues 7.5% to $17.6 billion and grew its operating income from $208 million (1.3% operating margin) to $276 million (1.6% operating margin). Its net income during the same period was nearly $1.3 billion.
“This is a once-in-a-generation investment in Michigan’s healthcare future and it reflects our commitment to making healthcare more personal, delivering extraordinary care and making it easier for people to access the services they need,” Decker said.
