What's around 300 Demott Avenue

About this property

A rare offering in Rockville Centre, set directly across from the storied Rockville Links Club, 300 Demott Avenue is a brick Georgian Revival Colonial completely reborn through a no-expense-spared renovation, offering approximately 4,097 square feet of refined living. A columned portico and circular drive make a grand first impression, opening to an expansive two-story entry foyer with a sweeping staircase and designer lighting. Principal rooms unfold beneath coffered ceilings, custom moldings, and rich trim, anchored by a fireplace and walls of French doors that frame the grounds. The chef’s kitchen showcases Thermador appliances, marble countertops, custom cabinetry, and a center island, flowing into a sunlit breakfast area and a light-filled sunroom with its own fireplace. From the living room, two sets of doors lead to an open porch overlooking the rear grounds, a built-in outdoor kitchen with a natural gas connection, and a classic rectangular in-ground pool with a brand-new blue liner. Upstairs, the primary suite features a tray ceiling, walk-in closet, and spa-inspired bath with marble shower, freestanding soaking tub, and double vanity, joined by generously scaled secondary bedrooms and a true second-floor laundry room. Rebuilt from the studs, the home boasts a newer roof, windows and exterior doors imported from Turkey, all-new plumbing and electric with 200-amp service, two-zone Rheem HVAC, a Navien boiler, Kohler fixtures, and Thermador appliances throughout. The finished lower level adds flexible living space with a half bath and private outside entrance. Outdoors, a paver patio wraps the pool, complemented by a detached two-and-a-half-car garage and professionally landscaped grounds, with the front lawn newly seeded and the rear grounds finished with fresh sod, all served by an in-ground sprinkler system. Thoughtful exterior lighting elevates the home day and night, including a grand chandelier at the columned portico, soffit lighting beneath the eaves, and rear-mounted floodlighting that washes the pool in a warm evening glow. A rare turnkey offering that pairs classic architecture with modern, top-to-bottom craftsmanship in one of Rockville Centre’s most sought-after locations.
