Property Description

Westhampton Beach Estate SectionPHOTOS COMING SOON. Located on one of the village's most prestigious lanes, in the heart of Westhampton Beach's estate section, this gracious home is just moments from Main Street. Built in 1930 and expanded in 1994, the seven-bedroom residence pairs beautiful original architectural details with a contemporary sense of space. A welcoming foyer opens to an expansive living room with beamed ceilings and an original marble fireplace, flowing into a distinctive octagonal sunroom and wraparound three-season porch. The main level also features a spacious dining room with bay windows and marble fireplace, connecting to the eat-in kitchen. Upstairs are seven bedrooms, most with en-suite baths, including a separate primary suite with an adjoining office and private staircase. Outside, a large deck provides plenty of room for dining and relaxing, while the gunite pool and surrounding deck create an inviting setting for summer days. A detached two-car garage, originally the property's carriage house, adds to the home's character. With its exceptional location, generous proportions, and original details, this is a rare opportunity to make a classic Westhampton Beach residence your own.
