Rare lot size. Private State Park access. Architect-crafted design. Welcome to 10 Lydia Lane in Menendez Park. Situated on nearly a third-acre lot in the sought-after Menendez Park community on Anastasia Island, this architect-designed residence offers privacy, character, and rare direct access into Anastasia State Park through a gated neighborhood entry. With more than 1,600 acres of protected beaches, tidal marshes, and dunes just beyond your gate, the setting is truly unmatched. Designed and built by its original architect-owner, the home reflects thoughtful craftsmanship and enduring construction. Distinctive ceiling details -- including tray, rounded, and oval designs -- add architectural depth and interest throughout. The updated kitchen blends style and function, while a gas fireplace and whole-house generator provide comfort and peace of mind. The primary suite occupies the second floor, offering privacy and an elevated perspective. An additional upper-level ensuite space provides flexibility for guests, studio use, or private retreat. A sculptural spiral staircase connects the upper levels, serving as both functional design and architectural focal point. At the top, a rooftop deck captures sweeping views and coastal breezes -- ideal for sunset evenings under the stars. Outside, the expansive backyard framed by mature vegetation offers rare space for a pool or future expansion. A 20' x 30' basement -- almost unheard of on Anastasia Island -- provides exceptional storage, workshop, or creative space. Hurricane-impact windows on upper levels and custom Bahamian shutters complete this distinctive island property.
