Supplements: Built in 2023 and designed by Scott Hughes of Hughes Umbanhowar Architects, the home offers over 5,000 square feet under air and more than 8,000 square feet total, constructed entirely of poured concrete for durability, storm resilience, and long-term structural integrity. Nearly 100 custom windows and 14 glass sliders allow natural light to move throughout the home, while polished concrete floors and clean architectural lines create a calm, modern environment without excess. A signature floating entry, framed by a shallow water feature, leads into a layout centered around a courtyard pool that anchors the home's indoor-outdoor living and creates complete privacy from surrounding areas. The property encompasses approximately two acres of total use, including an additional exclusive-use acre that enhances both privacy and overall utility. Outdoor features include the central pool, a separate spa area, landscaped grounds, and a private recreation field, along with direct access to both the Atlantic Ocean and the Intracoastal Waterway via private paths. This dual-access lifestyle is a key differentiator, offering both open water proximity and protected inland use. The home is equipped with Control4 smart home automation, multi-zone audio, motorized shades, and an expanded HVAC system designed for quiet and efficient climate control. The primary suite opens directly to the courtyard pool and is complemented by a spa-style bathroom, dual walk-in closets, and clean, functional design throughout. Elevated positioning provides both privacy and protection while maintaining close proximity to the ocean. Offered at $16,995,000, Casa D'Ändelös represents a compelling opportunity to acquire a recently built, architecturally significant estate with construction quality and land characteristics that would be difficult to replicate today on Jupiter Island.
