Welcome to 420 S Beach Road, a truly magnificent, private family compound centrally located in Jupiter Island. Originally known as ''The Quarry,'' this estate was completed in December of 2018 and sits on 2.7 acres of one of the highest elevations in Hobe Sound. 263 feet of Intracoastal frontage provide for stunning panoramic views of the Intracoastal and preserve. The outdoor amenities include a dock with a boat lift and a sandy beach area to the water. The property also comes with deeded beach access conveniently located a stone's throw away. An absolute first class, incredible team of Dailey Jenssen Architects, Onshore Construction, and Angela Reynolds Design helped to bring this brilliantly engineered plan to fruition. This is an extremely rare opportunity to own one of the more extraordinary properties in all of Jupiter Island.

''The Quarry'', a spectacular Jupiter Island estate, sits atop 2.6 highly elevated acres with 260' of Intracoastal frontage and offers wide water views across to the wildlife sanctuary. Green lawns slope down to where a dock could be installed to accommodate a yacht. Sitting at the highest point, the main house features beautiful views from the master, living room, dining room and study. Attached to the main house by a breeze way is a spacious two bedroom two bath guest house with a large living room over looking the pool and water. There is an additional two bedroom guest house on the property PLUS an apartment over the garage. This wonderful family compound surrounded by lush tropical landscaping and old growth trees provides natural beauty and privacy. Deeded beach access. If a buyer's preference is to build a new main house and guest houses to suit their specific needs, it is possible to construct approximately 11,000 s.f. in a main house and two additional separate structures. Sizes and measurements are approximate.
