In the coveted Sandy Hook Gulf Beach enclave of only 42 homes, this unique Mid-Century Modern home is now offered for purchase for the first time since 1983. The one-of-a-kind mid-century modern retreat rests on 1.6 acres of serene lakefront adjacent to where Big Sarasota Pass meets the Gulf of Mexico. Created by Frank Folsom Smith, a noted member of the Sarasota School of Architecture, this passively designed treasure was crafted from local cypress, oak, terra cotta and Ocala block and sits harmoniously within a lush Florida-native landscape alive with palms, cedars, and blooming wild flora. Nature lovers will delight in the lake along the southern edge of the property, home to a vibrant array of wildlife. The main residence, built in 1964 and lovingly preserved by its current owner since 1983, features timeless modernist design and abundant natural light through true north and south facing 10-foot glass sliders that welcome daylight. Meanwhile the interiors are shielded from direct sun for restful living. The guest house, added in 1987, also designed by the firm, complements the main home, together offering 5 bedrooms, 3 full bathrooms, 2 expansive great rooms, and a rare wood-burning fireplace, perfect for cozy winter evenings. Outdoors, all residents can enjoy their choice of sun-dappled terraces or shaded garden hideaways beneath more than 120 mature palms and cedars. Thoughtful upgrades ensure comfort and ease in this home's remodeled kitchen with all new appliances, new Trane HVAC systems covered by 10-year warranties, a 2025 deep-well irrigation system, and low-voltage outdoor lighting synchronized by the integrated atomic clock for effortless ambiance. Just a 150-meter stroll west through the trees leads you to Sandy Hook’s exclusive residents-only Gulf beach, a secluded paradise of sugarwhite quartz sand where sea turtles hatch annually and dolphins and manatees play offshore and sunsets paint the sky in vivid color. Conveniently located near Siesta Village’s boutiques and restaurants, and within easy reach of top-rated Sarasota County schools, The Out-of-Door Academy, and Sarasota Memorial Hospital, ranked among America’s top 50, this home offers the perfect blend of mid-century authenticity, privacy, and coastal lifestyle. This truly rare architectural offering is where Siesta Key’s natural beauty and Sarasota’s cultural soul meet the timeless artistry of mid-century design.
