Construction on One Carleton Green in Central Islip hits key milestones, turning a blighted lot into 96 affordable homes near the LIRR. The $65M project nears half-complete status ahead of 2027 finish.
One Carleton Green, the major construction project in Central Islip, is making fast progress on its 96-unit affordable housing development just steps from the Long Island Rail Road station on Carleton Avenue.
This $65 million mixed-use site, once a blighted industrial lot and old rail parking area, broke ground in October 2025. Now, in early 2026, crews are advancing on the three-story building with first-floor retail, two public plazas, and Teatro arts space for community events.
The project pulls $24.5 million from New York's Low-Income Housing Tax Credit Program, $6.4 million from the Middle Income Housing Program, plus funds from Suffolk County and the 2018 $10 million Downtown Revitalization Initiative. It targets households earning 30-100% of Area Median Income, with 15 units for those with developmental disabilities.
Developed by Georgica Green Ventures LLC, the all-electric complex includes laundry on each floor, EV charging stations, and utility allowances for residents. "This development is transformative, turning a vacant lot into a $65 million investment," said David Gallo, president and CEO of Georgica Green Ventures.
Nearby, the Town Hall Annex project on Nassau Avenue ramps up with closures starting March 10, 2026, at 7 a.m. for ADA ramps and new traffic patterns. Funded by federal ARPA money, it boosts accessibility, moves flood-prone items from the basement, and upgrades IT at the nearly 100-year-old Town Hall.
Islip Supervisor Angie Carpenter called One Carleton Green "a dream years in the making," crediting Governor Hochul, state partners, and Suffolk County. Construction wraps in 18 months, by 2027, sparking jobs and housing amid Long Island's shortage.
