3740 BAYOU LOUISE LANE, Siesta Key, FL, 34242 | $12,900,000

Tucked on the coveted north end of Siesta Key, this extraordinary double-lot point estate is positioned at the tip of a protected peninsula, offering panoramic water views and unforgettable sunsets. Surrounded by water and set directly across from protected parkland, the setting feels like your own private island. The property features three separate structures: a main residence, a guest house, and a separate waterfront cabana with bath. In total, the compound offers six bedrooms and six bathrooms, with gourmet kitchens in both the main house and guest house — each outfitted with high-end appliances throughout — ideal for multigenerational living, guest accommodations, or an exceptional private retreat. Throughout both residences, the finish detail is exceptional. Designer-selected materials create a cohesive and elevated aesthetic carried seamlessly across the entire compound. Custom wood flooring with intricate stone inlays, handcrafted stairwells featuring wood and stone risers, extensive crown molding, and refined architectural millwork highlight the level of craftsmanship invested in every space. Specialty stonework and thoughtfully curated finishes blend warmth with sophistication, creating interiors that feel timeless, substantial, and unmistakably high-end. Outdoor living is nothing short of spectacular. A dramatic infinity-edge pool with swim-assist system overlooks the water, enhanced by a striking waterfall feature that spills elegantly into the pool. New pool equipment (2025) supports the system. Natural rock waterfront frontage and a sculptural rock formation lead down to the shoreline, creating a one-of-a-kind coastal backdrop. Two docks serve the property — one with a double lift — offering outstanding boating access and rare protection on both sides of the point, with additional lift capacity for multiple watercraft. An outdoor shower provides added convenience after boating or swimming. Perched at the edge of the peninsula, the waterfront cabana and adjacent hot tub create a private, spa-like retreat suspended over the water — an unforgettable setting to take in sweeping sunset views. The residences were renovated separately: main house (2009) and guest house (2012). All A/C units have been renewed recently, along with the electric unit, and a new transformer (2024) services both properties. Sonos surround sound extends throughout all structures. Located on the highly desirable north end of Siesta Key, the estate offers convenient on-and-off island access while remaining just minutes from Southside Village and downtown Sarasota.
