A new 283-unit apartment building in Science Park expects to welcome its first tenants later this month — advancing a years-long project of redeveloping the former Winchester Arms factory complex into homes, stores, and bioscience labs.
Located at 315 Winchester Ave., the luxury rental complex is called The Winston.
According to the city’s online permit database, the Building Department issued a Partial Certificate of Occupancy to the five-story building on Dec. 10. The certificate only applies to The Winston’s 283 apartments and amenity spaces, not to its 12,500 square feet of commercial space.
A spokesperson for LMXD, one of the building’s developers, said tenants will begin moving into the building sometime in January.
On Friday, Jake Pine, a managing director at LMXD, said The Winston’s opening “marks the latest chapter in the ongoing revitalization of [the Science Park] neighborhood into a modern academic, economic, and residential hub.”
The Winston replaces part of an abandoned factory complex that was once owned by the Winchester Arms Repeating Company, an industrial giant of the 20th century. The building abuts Winchester Lofts, a 158-unit, upscale apartment building that may or may not be for sale. It’s also within walking distance of 398 new apartments at 201 Munson St., 176 new apartments at Cadence on Canal, and an active ex-factory demolition site at Munson and Mansfield.
Construction on The Winston, previously called Winchester Green, began in March 2024. It was led by the Science Park Development Corporation (SPDC): a nonprofit composed of Yale, the City of New Haven, the Olin Corporation, and the State of Connecticut. In early 2024, SPDC announced that they had raised $90 million for the project, from investors ranging from Goldman Sachs, an investment banking giant, to the Glendower Group, the housing authority’s nonprofit development affiliate.
Two years later, the SPDC celebrated The Winston’s Partial Certificate of Occupancy.
“The building offers a lifestyle that is both refined and welcoming, with thoughtfully designed residences, curated amenities, and immediate access to the energy, culture, and character of New Haven and Yale,” reads an email sent out by SPDC on Dec. 19.
According to The Winston’s website, apartments range from studios to three-bedrooms, each designed in a modern, open layout that features wood-like flooring and stainless steel appliances. Residents can spend time in a library, fitness center, clubhouse, and “resort-style pool.”
When plans for the building were presented in February 2024, neighbors questioned whether the complex would be affordable enough for long-time residents of Dixwell and Newhallville, two of New Haven’s historically Black neighborhoods.
In the end, said a spokesperson from LMXD, 57 units in The Winston have been designated as affordable.
Of those, 30 are allotted to residents earning 60 percent of the Area Median Income (AMI), 12 for residents earning 50 percent of AMI, and the remaining for residents earning 30 percent of AMI. Currently, a family of four making $67,920 would be classified as earning 60 percent of AMI, $56,850 as earning 50 percent of AMI, and $33,960 as earning 30 percent of AMI.
For the affordable units, monthly rent ranges from $351 for a studio to $1,287 for a three-bedroom.
For the market-rate apartments, total monthly leasing prices on The Winston’s website begin at $2,012 for a 490-square-foot studio, while the most expensive three-bedroom unit costs $4,657. Select apartments are currently eligible for two months of free rent.
The entrance to The Winston faces Winchester Lofts, another luxury apartment building in Science Park.
And, next to The Winston and Winchester Lofts, the SPDC is continuing to demolish the final portions of the former Winchester Arms factory complex.
