Property Description
Rare opportunity to acquire a unique property in the heart of historic Setauket within the Town of Brookhaven, Suffolk County, NY. Situated on an expansive parcel within the A-1 Low Density Residential District, the property offers a distinctive combination of existing improvements and potential future uses, subject to town approvals. The site is improved with a main church building along with several additional structures. The church and the residential building fronting Main Street, previously used as a monastery, date back to the late 1800s to early 1900s and are designated historic. The monastery building is currently vacant and in need for renovation. A second two-story residential structure situated toward the rear of the property was built in 1981 and has been recently renovated to include five bedrooms and two bathrooms. The property also contains several smaller free-standing structures that appear to be used for parking and storage purposes. The generous lot size and prominent Main Street location present a compelling opportunity for a variety of potential uses including continued institutional/religious use, residential conversion, or possible redevelopment, subject to zoning regulations and approvals from the Town of Brookhaven. Given the historic nature of a portion of the improvements, the path of least resistance may be to maintain the existing religious use while preserving the structures in place. With substantial site area and frontage along Main Street, the property offers a scale that is rarely available in the historic Setauket area. The depth of the parcel and the presence of multiple existing structures may provide flexibility for estate-style residential use, adaptive reuse, or other redevelopment concepts, subject to Town of Brookhaven zoning regulations and approvals. Properties with this combination of land size, location, and existing infrastructure are seldom offered in this established North Shore community. Ideally located within the highly regarded Three Village School District and just minutes from Stony Brook University, Stony Brook Hospital, Port Jefferson Village, and the Long Island Sound, the property benefits from strong surrounding home values and a desirable North Shore setting. Buyers are encouraged to perform their own due diligence regarding zoning, permitted uses, and potential subdivision or redevelopment opportunities.
