About this home

An exceptional estate in the heart of Back Lawrence, 150 Ocean Avenue is distinguished by its classic architecture, impressive scale, extraordinary grounds, and distinctive amenities. Inside, a double-height entry hall sets a gracious tone for a residence encompassing over 5,600 square feet, seven-plus bedrooms, four fireplaces, a finished third floor, and an elevator. A freestanding three-car garage, itself over 900 square feet, provides extensive storage, as does the full basement, with potential for additional finished space. Outdoors, the grounds feature a large in-ground pool, a Har-Tru tennis court, and a built-in grilling station with twin grills. Herringbone brick paths connect these outdoor spaces, while towering trees and lush plantings envelop the property, providing privacy and reflecting decades of careful cultivation. For all the privacy of a country estate, 150 Ocean Avenue is remarkably well connected. The Lawrence and Cedarhurst LIRR stations, local schools and shuls, and the Lawrence Yacht & Country Club are all just a short drive away.
