Work on Winchester Green, a planned mixed-income and mixed-use development in New Haven’s Science Park, will begin in the new year as the development team announced it has secured funding.

Winchester Partners, a joint venture of Twining Properties and LMXD, a national mixed-income developer, is building the $90 million Winchester Green development – a five-story building that will host 283 mixed-income apartments on an underutilized surface parking lot. The project will include 57 affordable units and 12,800 square feet of retail space.

Developers won permission to build 287 new apartments, two new privately owned streets, and a new public plaza — continuing the transformation of the former Winchester Arms factory complex into a research, residential, and shopping hub.

In its heyday, the former Winchester Repeating Arms factory was a bustling hub of economic activity for New Haven’s Newhallville and Dixwell neighborhoods, at one time drawing some 25,000 people a day into the area to work for the legendary rifle maker.

New York developer Alex Twining has big dreams of restoring the abandoned factory site and surrounding area to its former glory, making it a place where people will want to live, work, dine and shop.

Hundreds of new apartments. Tens of thousands of square feet of office and lab space. Ground-floor retail up and down Winchester Avenue.

Science Park’s redevelopers unveiled those plans to Dixwell and Newhallville neighbors as they prepare to embark on the next stage of turning the former Winchester Arms factory complex into a research, residential, and shopping hub.
