About Old Westbury
Home to the storied Old Westbury Gardens and its grand former estates, the village preserves a rare sense of space and privacy, with two-acre zoning and rolling, wooded lots. It's one of the North Shore's premier addresses.
At estate scale, the details matter most — millwork, materials and finish. We deliver kitchens, baths, additions and whole-home renovations to the standard these properties command.
