About This Home

4821-L Koloa Rd

Welcome to Iron Gate Ranch, an unrivaled equestrian estate where ultimate privacy, refined luxury, and modern sustainability converge on Kauai’s coveted South Shore. Encompassed behind a gated entrance on over 11 sprawling acres of prime agricultural land, this secluded compound offers a rare blend of tranquil island seclusion and incredible convenience, situated just five-minutes from the world-class beaches and resort amenities of Poipu Beach. At the heart of the estate sits an expansive, 4,200+-square-foot single-story residence designed to embody effortless indoor-outdoor living. The home offers four ensuite bedrooms—each with its own walk-in closet and direct exterior access. An impressive great room and an adjacent indoor/outdoor/wellness space, (including sauna and cold plunge) both open gracefully to a resort-style pool, spa and fire pit, creating an ideal backdrop for relaxation or entertaining. Designed for effortless living, the estate seamlessly blends cutting-edge technology with sustainable luxury. Energy independence is powered by a 38-panel photovoltaic solar array paired with a Tesla Powerwall battery backup system. Complete home control is provided through a state-of-the-art Savant automation system with an integrated Sonos sound system, while a six-zone central climate control system delivers year-round indoor comfort. Beyond the main residence, the estate includes dedicated equestrian facilities, multiple fruit trees, and plenty of space for agricultural pursuits. The property also offers the ability to construct an additional 1,000-square-foot secondary dwelling along with supplementary agricultural buildings. Whether envisioned as an active equestrian compound, a self-sustaining private sanctuary, or an expandable multi-generational estate, this landmark property offers an extraordinary lifestyle on Kauai.
