Greystar and Haseko begin work on 189-unit complex at 100 West St.

Needham, MA Greystar, a global leader in investment management, development, and property management, and Haseko North America, the U.S. subsidiary of Japan’s largest condominium construction firm, have begun construction activity on a new multifamily development located at 100 West St. The 189-unit complex represents the second partnership between the firms and was proposed in accordance with the town’s newly outlined zoning under the MBTA Communities Act. 

“Greystar is delighted to commence work on 100 West St. to deliver more housing at a time where the need has never been greater,” said Gary Kerr, senior managing director of development at Greystar. “Through its MBTA Communities Act rezoning, the town of Needham has made the entitlement process incredibly straightforward, and we are grateful for their engagement to this point. Greystar is also excited to build on the relationship with Haseko, and we appreciate their continued partnership.”

Formerly an assisted living facility, the redevelopment of 100 West St. is thoughtfully designed to integrate with the surrounding retail and residences. The community, which is being constructed to Passive House standards, will offer a distinct product featuring direct entry units at the ground level and a step back that introduces new green space along Highland Ave.

Upon completion, 100 West St. will feature a mix of studio, one-, two-, and three-bedroom apartments. Amenities will include a fitness center, library, lounge space, package room with cold storage, and a golf simulator. Additional features, like a dog run, playground, community garden, and two pocket parks will complement the offerings. The community will also have dedicated bike parking as well as parking for vehicles.

Future residents of the community will benefit from the exceptional convenience and walkability that is uncommon in comparable suburban settings. Directly across Highland Ave. sits a grocer (Trader Joe’s) and pharmacy (CVS) while the Needham Heights Commuter Rail stop, providing direct access to downtown Boston, is situated across West St. The community is also located less than a mile from Rosemary Lake and the Needham Free Public Library. 

Greystar and Haseko first collaborated on Birchway Elk Grove, a new multifamily development located in Elk Grove, California, that is expected to deliver mid-2026. 100 West St. represents Haseko’s first foray into the northeast region of the United States.

Demolition is currently underway, and construction is planned to begin in spring. The project is anticipated to deliver in fall 2027. 

“After a successful west-coast ground-breaking, we are excited to partner with Greystar once again. The northeast is an important expansion market for our firm and believe 100 West St. is the perfect project to begin this journey” said Kain Matsumoto, Chairman and President of Haseko North America. “We look forward to furthering this important relationship as we strive to reach $100 million in annual profit”.

“We would like to thank the Greystar team for envisioning such a creative infill project and working with local stakeholders to bring it to life” added Laurie Mathers, Head of Investment & Asset Management at Haseko North America. “The unrivalled walkability and contemporary design will create an attractive leasing proposition for future tenants”.
