For the first time in more than 75 years, a legacy of land assembled over generations is being offered to the public. Beginning with the acquisition of its first parcel in 1949, what started as a single investment has evolved into a remarkable nine-parcel assemblage encompassing approximately 4.21 acres in the heart of the Ronkonkoma/Nesconset corridor. Never before offered as one acquisition, this is a once-in-a-generation opportunity to control an entire mixed-use portfolio with exceptional flexibility and long-term potential. More than just real estate, this is the opportunity to shape the future of an entire development block. Whether your vision is a thoughtfully planned residential community, a mixed-use redevelopment, an income-producing investment portfolio, or a phased development strategy, this offering provides a foundation that would be extraordinarily difficult to recreate in today's market. The assemblage includes: • Two commercially zoned parcels with prominent frontage and visibility along Smithtown Boulevard. • A six-unit multifamily property providing immediate income while future plans are developed. • Five contiguous residential development parcels totaling approximately 2.75 acres, offering exceptional potential for future residential expansion. • A single-family residence that may serve as rental property, or future redevelopment component. What makes this offering truly exceptional is not simply the acreage—it's the opportunity. Acquiring nearly an entire development block under one ownership eliminates the time, uncertainty, and expense of assembling multiple properties from different owners. It creates a level of flexibility and control that is increasingly difficult to find in today's market. Strategically positioned with frontage on Smithtown Boulevard and additional access from Spectacle Lake Drive and Lillian Drive, the property enjoys outstanding visibility, multiple access points, proximity to Lake Ronkonkoma, the Long Island Rail Road, shopping, dining, major transportation corridors, and regional employment centers. Very few opportunities offer this combination of location, existing income, commercial frontage, residential development potential, and long-term flexibility within a single acquisition. For more than seven decades, this property has been part of one family's story. Today, it is ready to become part of someone else's vision. All information is deemed reliable but not guaranteed. Buyers are responsible for independently verifying zoning, permitted uses, development potential, approvals, utilities, lot dimensions, environmental conditions, and all other matters material to their intended use.

A rare offering of 4.36 level acres just moments from the boutiques, restaurants, and ocean beaches of East Hampton. Perfectly positioned across from the iconic LongHouse Reserve and its 16 acres of sculpture gardens and serenity, this exceptional property presents a unique opportunity to create a private estate of distinction. With an expansive building envelope and generous clearing allowances, the groundwork is set for a remarkable vision. Permits are ready to be pulled for a thoughtfully designed modern residence spanning approximately 16,000 +/- square feet across three finished levels-crafted to harmonize with the surrounding landscape while delivering every luxury expected of a Hamptons retreat. The proposed home features 9 bedrooms, 10 full and 2 half baths, and an array of resort-caliber amenities. A dramatic double-height entry opens to an airy, open-concept living space anchored by a double-sided fireplace and soaring window walls overlooking the grounds. An oversized eat-in kitchen with dual islands flows seamlessly into the formal dining room and den, each with walls of glass leading to patios and sweeping lawns. The main level also includes a separate family room, one of two primary suites, a generous mudroom with pantry, and access to the attached two-car garage. Upstairs, six en-suite bedrooms include a second luxurious primary suite complete with dual closets and a spa-like bath featuring double vanities, a glass-enclosed shower, soaking tub, and private water closet. The finished walkout lower level is designed for recreation and relaxation, offering a state-of-the-art theater, gym, sauna, spa, and steam room. An expansive lounge with kitchenette provides the ideal setting for entertaining, while two additional en-suite bedrooms and a secondary laundry complete the level. Outdoors, the property delivers the ultimate Hamptons trifecta: pool, pool house, and tennis. A heated gunite pool and spa are surrounded by ample patio space for large-scale entertaining. The sleek pool house with covered lounge area overlooks both the pool and the tennis court beyond-creating a seamless indoor-outdoor lifestyle experience. Embrace the approved plans or reimagine the possibilities. This is a rare chance to build a legacy estate on one of the most compelling parcels near the Village.
