Greystar broke ground on 437 Whittenton St. in Taunton. Once completed, the 390-unit development will be the largest modular residential project in the Commonwealth, according to a press release.

The site’s abandoned 19th-century mill buildings will be demolished and replaced by 10 residential buildings featuring a mix of one-, two- and three-bedroom apartments. Prefabricated modules sourced from Modern Living Solutions will speed up the construction process.

Greystar first used modular construction at a Pennsylvania project in 2024, later adding 1,734 modular units across the Northeast.

“Greystar is thrilled to begin our efforts to redevelop an underused site and leverage our modular construction capabilities to bring much-needed housing to the Taunton community and enhance the Whittenton Mills site’s connection to the surrounding area,” said Ryan Souls, managing director of development at Greystar. “As Greystar remains committed to helping increase housing supply in the Commonwealth, we look forward to continuing our work alongside the Taunton community to bring essential housing stock to the area.”

Community amenities at 437 Whittenton Street will include a clubhouse, pool, dog park, putting green and playground. Along with 1.5 acres of public green space, a community garden and retail opportunities may be added to the neighborhood, according to developers.

Resident move-ins could begin as soon as spring 2027, with final delivery expected in fall 2027.

“This project represents a major investment in the future of Taunton and the continued revitalization of the Whittenton neighborhood,” said Taunton Mayor Shaunna O’Connell. “For decades, the Whittenton Mills site has sat vacant and underutilized. Through this redevelopment, we are transforming a blighted property into new housing opportunities, public green space and economic activity that will benefit our community for years to come.”
