The bottom line: Boston is rebuilding its medical core in public, one state approval at a time. Three megaprojects are moving through the Longwood Medical Area at once — Mass General’s Ragon Building, the region’s first dedicated adult cancer hospital, and a replacement for the Brigham’s 50-year-old inpatient tower — while the rest of the system absorbs the collapse of Steward Health Care, which closed two Massachusetts hospitals and sold six more in a single autumn. Every one of those projects passed through the same gate: the Determination of Need, the most consequential construction review in American healthcare, in the state that also holds its hospitals to a 3.6% cost growth benchmark and then watches them exceed it four years running. For the facilities, design, and construction teams who work this market, Boston is not a building boom. It is a building boom with a docket number.

The capacity crisis is the client
Every project in this brief traces back to the same arithmetic. In April 2024, federal data counted 27 Massachusetts hospitals at 90% occupancy or higher, with 10 more at 85% or above — functionally full. Mass General Brigham’s pre-filed testimony to the Health Policy Commission described its own academic medical centers at “capacity disaster” status 95% of the time in fiscal 2024, an average of 102 patients boarding in its emergency departments daily, and 1,836 community inpatient transfers declined for lack of beds. The Health Policy Commission’s own analysis found 39% of behavioral health ED visits in early 2024 lasted longer than 12 hours.
The pressure is not a Boston-only phenomenon, and neither is the response. In Worcester, UMass Memorial’s North Pavilion — a $220 million conversion of a former rehabilitation facility into 72 private acute-care beds — opened in January 2025 and filled every bed within its first week; a build-out of shell space for 24 more rooms is already under construction. A converted building, full in seven days, is the cleanest demand signal in Massachusetts healthcare. Boston’s towers are the same signal at larger scale.
Three megaprojects in one medical district
The Ragon Building at Massachusetts General Hospital is the largest construction project underway in the city: two towers — the 17-story Chambers tower and the 15-story New Balance Foundation tower — on a shared five-story podium at 55 Fruit Street, with six below-grade levels bringing the total program to roughly 1.8 to 2.0 million square feet. The clinical program is a conversion as much as an expansion: 482 private single-bed rooms replacing mostly double rooms, 23 cardiovascular operating and interventional rooms, 100 infusion bays, and 120 exam rooms, supported by philanthropy that includes $200 million from Phillip and Susan Ragon, $100 million each from Herb Chambers and the New Balance Foundation, and $35 million from Irving Oil. MassDevelopment issued $865.5 million in tax-exempt bonds for Mass General Brigham in May 2026, funding the Ragon alongside the Faulkner campus redevelopment. Cost estimates for the Ragon range from about $1.9 billion to $3.1 billion depending on whether the underground and parking scope is counted — a spread worth stating plainly, because the project is large enough that both numbers circulate as “the” price. MGB says first patients arrive in the first tower in fall 2027; the Boston Globe has reported 2028. The second tower follows, with opening expected in 2030.
Two blocks away, the region’s first dedicated adult inpatient cancer hospital is rising — and its existence is a story about institutional divorce. Dana-Farber Cancer Institute and Brigham and Women’s spent years planning a joint cancer tower before splitting in 2023 over control of beds and development. Dana-Farber instead partnered with Beth Israel Deaconess Medical Center: a 14-story, 450,000-square-foot hospital at One Joslin Place with 300 inpatient beds across 10 inpatient floors. The Public Health Council approved its Determination of Need unanimously on March 20, 2025 — over Mass General Brigham’s request to cap the project at 126 beds — at a DoN-recorded capital cost of $1,675,700,000, with $83,785,000 directed to Community Health Initiatives. Construction began March 16, 2026, with deconstruction of the former Joslin Diabetes Center; completion is expected in fall 2030 and the first patient in 2031.
The third project is the Brigham’s answer to its own aging core. On September 30, 2025, Mass General Brigham announced it will replace the Braunwald Tower — 564 beds, roughly 50 years old, mostly double rooms — with a new complex-care inpatient building on the Francis Street campus, rendered as two towers of about 10 stories on a shared podium. The stated logic is concentration: centralize the sickest patients at the Brigham and free capacity at its smaller hospitals and emergency department. No cost, square footage, or filing has been disclosed; beds are targeted for the 2030s. Around the megaprojects, the opened work proves the direction: the Brigham and Women’s Faulkner addition in Jamaica Plain (78 single-occupancy rooms, inpatient capacity up more than 45%, opened June 2025) and BIDMC’s Klarman Building (158 single-bed rooms, opened April 2023, its first new building in 27 years). The single-bed conversion of Boston’s academic core is the program of the decade, and it is happening one DoN at a time.
The gate: how the Determination of Need decides what Boston builds
Massachusetts is the anti-Colorado. Where Denver’s systems build on licensure and speed, Boston’s build on permission. A hospital project above $27,668,903.99 in the current fiscal year — the threshold is published to the cent — requires Determination of Need approval from the Department of Public Health under 105 CMR 100.000, and the standard approval condition dedicates at least 5% of the capital spend, over five years, to Community Health Initiatives in the communities the system serves. The Dana-Farber approval’s $83.8 million community commitment is that condition at megaproject scale.
The gate has teeth, and the record shows them. In April 2022, Mass General Brigham withdrew three suburban ambulatory DoN applications totaling $223.7 million after DPH staff indicated they would not recommend approval. And the state’s cost discipline runs parallel to its construction gate: the Health Policy Commission’s 3.6% cost growth benchmark has now been exceeded four consecutive years (actual growth of 5.7% in 2024, on $83.3 billion of total health care spending), and the Commission imposed the first Performance Improvement Plan in its history on Mass General Brigham in 2022 — a $176.7 million savings target that MGB reported exceeding, with $197.1 million saved, before the HPC voted the plan successfully closed in December 2024. For project teams, the practical translation is that a Boston hospital project is two projects: the building, and the regulatory case for the building — need, cost impact, community benefit, and the alternative of not building, argued in public before the first drawing is final.
The Steward shock, and the map it left behind
Underneath the Longwood cranes, the region is still absorbing the largest hospital failure in Massachusetts history. Steward Health Care — then the state’s third-largest system, with eight Massachusetts hospitals — filed Chapter 11 on May 6, 2024. On August 31, 2024, Carney Hospital in Dorchester (91 beds) and Nashoba Valley Medical Center in Ayer (38 beds) closed after drawing no qualified bids. On October 1, 2024, the remaining hospitals transferred in a single coordinated rescue: St. Elizabeth’s in Brighton and Good Samaritan in Brockton to Boston Medical Center for $140 million; Saint Anne’s in Fall River and Morton in Taunton to Brown University Health for $175 million; Holy Family in Methuen and Haverhill to Lawrence General Hospital for $28 million — roughly $343 million combined, preserving more than 13,000 jobs. When Apollo’s real estate arm rejected BMC’s bid for the St. Elizabeth’s property, the Commonwealth took the campus by eminent domain and turned it over to BMC; the hospital now operates as BMC Brighton.
The aftershocks are measured in minutes. In the Nashoba Valley, the Working Group that studied the closure region found median EMS transport times rose from 12 to 17 minutes after Nashoba Valley Medical Center closed — up to roughly 30 minutes from Ayer and Groton — and emergency volumes at neighboring hospitals jumped by double digits in the first month. UMass Memorial has committed to a satellite emergency facility in Groton in response. And the region’s strangest open file sits in Norwood, where the hospital has been closed since a 2020 flood: its rebuild approval was revoked in fall 2024, its owner reports about 75% of a replacement core and shell complete with more than $350 million spent, and legislation enacted in August 2026 gives the owner until November 1, 2026 — days from now — to reach agreement with a qualified nonprofit operator, or the state may take the property by eminent domain. Boston’s building wave and its closure map are the same story: capacity is being rebuilt where the approvals, capital, and academic gravity are, while the communities that lost hospitals negotiate from a much weaker hand.
Behavioral health is the fastest build-out in the region
The one service line growing faster than the academic towers is behavioral health, and it is growing in every direction at once. Boston Children’s is building a $640 million, 116-bed pediatric psychiatric hospital on the Franciscan Children’s campus in Brighton — roughly doubling its inpatient psychiatric capacity, with partial-hospital and intensive outpatient programs, ground broken in 2026 and opening expected by 2029. Tufts Medicine’s 144-bed behavioral health hospital in Malden, a $65 million joint venture with Acadia Healthcare on the former Malden Hospital site, opened in early 2026, consolidating the legacy services of two community hospitals. Boston Medical Center’s Brockton Behavioral Health Center (82 beds) opened in 2022, and Cambridge Health Alliance expanded its inpatient psychiatric capacity by about 75% in 2023 while opening community behavioral health centers in Cambridge and Malden. The demand behind the bricks is the boarding crisis: with hundreds of behavioral health patients waiting in emergency departments for placement on any given day, every one of these buildings was effectively full on paper before it opened.
The local layer is water
Boston’s amenity layer is not retail. It is the harbor. The city’s Article 25A Coastal Flood Resilience Overlay District — adopted in 2021 — requires essential and high-risk structures to set their lowest floors at the sea-level-rise design flood elevation plus two feet of freeboard, mapped against a 2070 storm with 40 inches of sea-level rise. The region’s hospitals have been building to that future for a decade: Spaulding Rehabilitation Hospital in the Charlestown Navy Yard, opened in 2013, set its first floor 30 inches above the 500-year flood level, put its mechanical systems on the roof, and installed on-site cogeneration that repaid its cost within ten years. The Ragon Building is designed to operate off-grid for up to four days as a disaster refuge and targets LEED Platinum; the Faulkner addition pairs a 950-space garage with 49 EV chargers and a solar array supplying about half its power. In Boston, resilience is not a sustainability chapter in the annual report. It is a design discipline with a flood elevation attached, and it prices into every project the way seismic prices into California.
The amenity layer: housing and feeding an imported city
No American medical district imports more people per acre than Longwood, and its amenity economy is sized to match. Boston Children’s runs family housing of its own: the Yawkey Family Inn, a 22-bedroom house a few blocks from the hospital in Brookline, which together with the Devon Nicole House serves nearly 1,700 families a year, coordinated through the hospital’s Patient Family Housing Program. A few streets over, the Inn at Longwood Medical keeps 155 hotel rooms inside the district itself, above the Longwood Galleria food court and an on-site CVS — lodging, food, and pharmacy stacked into one medical-district building.
The food layer is just as distributed. Dana-Farber puts a named dining pavilion — the Lavine Family Dining Pavilion — on the third floor of its Yawkey Center, with a specialty coffee roaster, For Five Coffee, in the Dana Building; the Starbucks inside Beth Israel Deaconess’s Shapiro Center opens at 5:30 on weekday mornings, before most of the district’s clinics; and Mass General spreads a set of cafes and coffee counters — the Eat Street Cafe, Coffee Central, and Tea Leaves and Coffee Beans among them — across its main-campus lobbies. Each is a small retail operation with a clinical landlord, run under infection-control rules in buildings that were drawn for medicine first.
That is the design problem Boston keeps posing: in a district where land is the binding constraint, amenity space competes for the same square footage as clinical space, and on the newest projects it is programmed from the first test fit rather than squeezed into what is left. Facilities teams here manage restaurants, a hotel, and family housing alongside the towers — a portfolio inside the portfolio.
What this means for design and construction teams
DoN fluency is the first competency. The teams that win Boston work are the ones whose planning starts at the application — programming that anticipates the need case, the cost and market impact review, and the community health commitment, because the approval conditions shape the building: what’s in it, where, and what the 5% funds in the surrounding neighborhoods. A design that cannot survive a Public Health Council hearing is not a design; it is a rendering.
Second, plan for the decant decade. The Ragon, the cancer hospital, and the Braunwald replacement all land in the same few Longwood blocks across the same ten years, in and around hospitals that are running at capacity-disaster occupancy while they build. Phasing, swing space, and enabling work — the Faulkner addition and the Klarman Building were both, in part, capacity chess moves for the larger game — are where this market’s risk and margin live. Third, the workforce constraint is the oldest open item: the Massachusetts Health & Hospital Association counted 19,000 unfilled acute-care hospital positions statewide in its April 2023 report, the most recent system-wide census of its kind, alongside roughly $1 billion in projected travel-labor spending. Three years on, the buildings have gotten bigger and the pipeline of people to staff them has not visibly caught up — 1,000 construction jobs are attached to the Ragon Building alone. Boston will finish these towers. The open question the whole market shares is who works in them.
Frequently asked questions
What is a Determination of Need?
Massachusetts’ certificate-of-need program, run by the Department of Public Health. Hospital capital projects above a published expenditure threshold — $27,668,903.99 for FY2025–26 — cannot proceed without DoN approval from the Public Health Council. Approvals carry conditions, most visibly the requirement that at least 5% of the capital spend go to Community Health Initiatives over five years.
How much does the Ragon Building cost?
Published estimates range from about $1.9 billion to $3.1 billion, and the difference is mostly scope: the lower figures describe the clinical towers, the higher figure includes the six below-grade levels and parking program. Anyone quoting a single number for the project should be asked which scope they mean.
What happened to Steward Health Care’s Massachusetts hospitals?
Steward filed Chapter 11 in May 2024. Two hospitals — Carney in Dorchester and Nashoba Valley in Ayer — closed on August 31, 2024. Six others transferred to new operators on October 1, 2024: two to Boston Medical Center, two to Brown University Health, and two to Lawrence General Hospital, for about $343 million combined. Norwood Hospital, closed since a 2020 flood and mid-rebuild, remains unresolved under an August 2026 state law with a November 1, 2026 deadline.
When does the Dana-Farber cancer hospital open?
Construction began March 16, 2026 and is expected to complete in fall 2030, with the first patient in 2031. The 300-bed hospital, a Dana-Farber and Beth Israel Deaconess partnership, was approved unanimously by the Public Health Council in March 2025 at a DoN-recorded capital cost of about $1.68 billion.
Why is every new Boston hospital room a single?
Because the stock being replaced is mostly double rooms — the 50-year-old Braunwald Tower is the emblem — and modern infection control, patient privacy, and family presence standards all assume single occupancy. The Ragon’s 482 rooms, Klarman’s 158, and Faulkner’s 78 are conversions of capacity as much as additions to it, which is precisely why the region can build this much and still feel full.
Healthcare Facility Hub tracks the standards, surveys, and construction practice behind projects like these — Determination of Need strategy, behavioral health design, ICRA containment, and the codes these buildings are held to. If you work in Boston-area facilities, design, or construction and see something here that needs correcting or sharpening, we want to hear it: talk to the Hub — facility leaders’ corrections make these briefs better, and we credit contributors by name and organization, or anonymously, as they prefer.
