CHARLESGATE Named Property Management Partner for Massachusetts' Largest Office-to-Residential Conversion

Synergy's Altitude in Worcester welcomes first residents September 1; CHARLESGATE leases up the 198-unit Fallon Health HQ conversion

WORCESTER, Mass. — The former Fallon Health headquarters at 24 Elm Street reopens this fall as Altitude, and CHARLESGATE Property Management (CPM) is the operating partner running its lease-up.

An eleven-story office tower has been tastefully converted into 198 studio, one-, and two-bedroom apartments at a project cost of roughly $73 million, the largest office-to-residential conversion in Massachusetts to date, developed by Synergy. The construction is done. What's left is lease-up: whether 198 units actually lease, hold rent, and stabilize before the market moves on.

"On the largest office-to-residential conversion in Massachusetts, we didn't need a vendor; we needed a partner who owns the outcome with us. CHARLESGATE has been that from day one," Said Rachel Kirby Sandeman, Chief Marketing Officer at Synergy, "They tell us what the Worcester market will actually bear, not just what we want to hear, and they've built the lease-up plan around our goals for the asset, not their scope of work. When 198 units have to lease, that honesty and ownership is exactly what you want on your side."

"A project like Altitude deserves nothing but the very best partners to achieve and exceed its pro-forma goals, and we're thrilled to be a small part of what makes this project so impressive and special," said Todd Mikelonis, President of CHARLESGATE Property Management. "Our Team-Powered Operating Model has already taken flight on-site at Altitude: one team, accountable for lease-up from first click to signed lease, not split across a marketing vendor and a leasing office working off different numbers."

After 20+ years of successful lease-ups, CHARLESGATE knows that demand generation of this magnitude happens when leasing, marketing, and on-site operations report to one accountable team rather than being split across vendors.  Naturally, CHARLESGATE's in-house marketing and creative agency, Authentic, was the first choice to lead the brand and go-to-market efforts while the conversion was underway.

The numbers on Altitude Worcester:

  • 198 units: 72 studios, 85 one-bedrooms, 41 two-bedrooms
  • Rents from $1,895 (studio) to $4,100 (two-bedroom); units from 404 to 1,211 square feet
  • Amenities: rooftop deck, fitness center, pool, underground parking, coworking space, reservable dining room, pet spa
  • Financing: $47.57 million from Washington Trust; a $3.6 million MassDevelopment HDIP bridge loan; a separate $4 million HDIP award; a $3.6 million Commercial Conversion Tax Credit from the Massachusetts Executive Office of Housing and Livable Communities; a 15-year property tax exemption from the City of Worcester
  • Ribbon cutting: fall 2026

Public money is betting that converting empty office space into housing works as policy. CPM's job is proving out the operating half of that bet: getting 198 new units leased at a pace that makes the underwriting real.
