Set on an extraordinary 140' x 430' oceanfront double lot, this custom-built coastal estate represents a rare convergence of scale, privacy, and craftsmanship with panoramic ocean views from both levels of the home. Built in 2015 by highly regarded local R Popovitch Builders, the residence showcases exceptional quality construction and high-end finishes throughout, on an elevated parcel with dune and revetment wall. The 5,000sq ft main home offers 5 bedrooms and 6 baths, thoughtfully designed to accommodate both grand entertaining and comfortable everyday living. Expansive, light-filled interiors are oriented to capture sweeping ocean views, with seamless flow between living, dining, and outdoor spaces. Guests will enjoy two generous first level bedrooms, one with vaulted shiplap ceiling. The spacious upper level contains a media room with views of Barnegat bay to the west and 3 more bedrooms (including the master) along the east side of the home, each leading out to an oceanfront balcony. A unique feature of the property is the 738sq ft detached guest annex and 3 car garage, complete with 4 additional bedrooms and a full bath--ideal for extended family, guests, or private staff quarters. This separate living space enhances both flexibility and privacy, creating a true compound-like setting rarely found along the Jersey Shore. The impressive lot dimensions provide an unmatched sense of space and opportunity, allowing for resort-style outdoor living just steps from the beach. Whether hosting large gatherings or enjoying quiet coastal mornings, the property delivers a lifestyle defined by comfort, elegance, and exclusivity. A truly exceptional oceanfront offering--where size, location, and craftsmanship come together to create one of Mantoloking's most compelling estates.
