Designed by a Yale architect and custom built in 2014, this truly one-of-a-kind home offers exceptional flexibility, modern efficiency, and a low carbon footprint in New Haven's West River neighborhood. Currently used as a single-family residence, the property presents multiple options, including a single-family, a single-family with an in-law, teen or primary BR suite, or a two-family configuration. The thoughtfully designed main level features high ceilings and an open-concept living room, dining area, and kitchen with island, along with a full bath & doors to the patio. The second level offers a bedroom, built-in desk area, and laundry. The third floor is a studio complete with kitchenette, full bath, laundry and an additional exterior entrance. Adding an interior door would easily create two distinct living spaces. Custom built-ins throughout maximize storage and functionality on every level. Outside, the charming front garden with raised beds interspersed provides a welcoming retreat, while the backyard patio with grill and fire pit create the perfect setting for relaxing or entertaining. Split systems on each floor for efficient heating and cooling and a private driveway provides off-street parking. Conveniently located just minutes from Yale University, downtown New Haven, restaurants, shopping, and major highways, this unique property offers an outstanding opportunity, for homeowners, multigenerational living, or investors.
