Annual single-family pool home available for lease in Sanderling Club Siesta Key! The Ness House, originally built in 1961 via John Lambie Sr.'s innovative Lambo lithic poured concrete method and renovated in 1971 with architect Tim Seibert, exemplifies Sarasota School of Architecture. It boasts an advanced rainwater collection system, natural cooling via roof outlets and north-facing walls, and earned historic designation in 2011. This waterfront retreat on nearly an acre with 135 feet along Heron Lagoon blends Seibert’s vision with contemporary design amid lush subtropical surroundings. The 4,006-square-foot home, meticulously renovated for flow and entertaining, features minimalist white tile floors, abundant skylights and seamless indoor-outdoor transitions. A gallery-style foyer highlights the architecture and beyond lies a versatile lounge (convertible to office/guest room) with walk-in closet, floor-to-ceiling windows, built-ins and private entrance. The expansive family area includes a great room, seating, and reimagined kitchen with Samsung induction cooktop, built-in oven/refrigerator, quartz walk-in pantry and dramatic tiled backsplash framing nature views. The retractable-glass Florida room adapts for intimate or open-air gatherings. The primary suite offers seating, sleeping and dressing zones with spa-like en-suite: wood accents, stone counters, soaking tub and walk-in shower. Three guest bedrooms (two with private courtyards; one en-suite, two sharing a stylish bath) ensure comfort. Outdoor spaces shine with covered kitchen, bar, grill, beverage area, lounge/dining zones, and open yoga/meditation area. Native landscaping, shell hardscape, and unique Ipe wood treehouse embody enduring Sarasota School principles. The gated Sanderling Club features 24/7 security, private beach and marina, membership is included along with lawn and pool maintenance.
