1510 Grand Avenue Rare Opportunity. Extraordinary Scale. Endless Possibility. Welcome to one of North Baldwin's most commanding residences -> A magnificent single-family estate spanning over 5, 800 square feet of living space on a nearly 13, 000 sq ft lot, offering the kind of size, stature, and versatility that simply doesn't exist at this price point on Long Island. From the moment you arrive, this home makes a statement. Grand proportions, generous room sizes, and a layout designed for a life well-lived; this is a home that accommodates everything: multigenerational living, lavish entertaining, and a lifestyle that doesn't require compromise. What truly sets this property apart is its separate private entrance. Ideal for a home-based professional practice (medical, legal, wellness, therapy); allowing you to seamlessly separate work and home life without ever leaving the property. This dual-purpose functionality is extraordinarily rare. Inside, the sheer volume of space speaks for itself. Multiple living areas, 8 Bedrooms, 5 bathrooms, a finished basement, and a 2-car garage -> EVERY square foot thoughtfully used. Whether hosting holiday gatherings or unwinding in your own quiet wing, this home flexes to fit your world. Outside, nearly a quarter-acre of Nassau County land delivers the outdoor space Long Islanders dream about. Room to entertain, landscape, or simply breathe. Location seals it: nestled in North Baldwin, within the Baldwin Union Free School District, minutes from the LIRR with Manhattan just ~38 minutes away, and close to Jones Beach, the Southern State Parkway, and all the shopping and dining Grand Avenue has to offer.
