A rare opportunity to own an original, one-owner contemporary eco-home built in 1982 and celebrated for its timeless design and superior construction. Set on 1.7 acres with 170' of St. Johns River frontage, this concrete block home features soaring ceilings, exposed beams, and a sunlit central gathering space surrounded by windows. Enjoy a unique walk-up astro turf rooftop perfect for stargazing or sunset views. Indoors, a dedicated spa/exercise room with hot tub adds to the wellness appeal. Outside, a striking pool design features a decorative bridge, complemented by a covered picnic pavilion. Boaters will love the private dock with covered boat lift. Perched on a high bluff beneath mature oaks and magnolias, this cul-de-sac retreat offers both privacy and prestige in a neighborhood of fine riverfront homes.
