Own one of the last remaining multi-acre parcels of the original Jagger estate - a unique Hamptons compound where 1920s character meets modern architectural sophistication, set on 8.36 private acres across 5 parcels in Westhampton: a combination that simply does not exist elsewhere in this market. At the heart of the property, 18 Jagger Lane sits on 4 of the acres and comprises the main residence, a studio, a gunite pool, a pool cabana, and manicured grounds defined by mature specimen trees, curated plantings, and established landscaping that would take years-and significant investment-to achieve today. The well-maintained 1929 shingled Dutch Colonial offers 3,323 SF of beautifully proportioned living space, with four bedrooms, 4.5 baths, and an attached two-car garage. The residence reflects its original architecture while incorporating the finishes and amenities expected today, including a chef's kitchen newly renovated in 2022 with a 6- burner Blue Star range and a 10'9" x 3'6" quartz island, a library with custom built-ins, multiple living spaces with fireplaces and sliders to the mahogany deck, and a private primary wing with dual baths, walk-in closets, laundry, and its own deck overlooking the magnificent pool. The second floor offers an ensuite guest bedroom and two additional bedrooms sharing a bath. Outside, a gated entrance opens to a series of distinct gardens, each unfolding into the next, creating depth, privacy, and a sense of discovery across the grounds. A separate studio serves as an office or guest retreat, complete with wide plank floors, a wood-burning stove and a private garage while the 44 x 22- foot gunite pool, accessed through a garden gate, is complemented by a cabana straight out of Hollywood, including changing rooms, kitchenette, outdoor shower and twin pergolas, framing a covered outdoor living space. Four additional parcels, including 2 buildable lots, complete the estate: 20 Jagger Lane (0.9 acres), 24 Jagger Lane (0.9 acres), 22 Jagger Lane (1.4 acres), and 47 South Country Road (1 acre) offering extraordinary development potential for a compound, guest houses, or future investment. The four lots may be sold separately. For the discerning buyer who understands that value is measured in acres, privacy, and provenance, this is the one.
