3131 BAYOU SOUND, Longboat Key, FL, 34228 | $1,650,000

Wrapped in lush, mature landscaping and set along a tranquil mangrove-lined canal, this waterfront 3BR/2. 5BA residence on Longboat Key offers space, privacy and an inviting canvas for future vision. A circular paver driveway and stepped front entry create a gracious arrival, framed by tropical greenery and a classic barrel tile roof. Inside, cathedral ceilings with exposed beams, clerestory windows and a wall of glass sliders fill the great room with natural light. A corner fireplace adds warmth and character, while the open layout feels airy and welcoming. Sliders extend the living space outdoors to a wood deck shaded by a pergola, where peaceful canal views set a calming backdrop for everyday living. The kitchen brings a distinctive mid-century influence, featuring low-profile black-and-white cabinetry, a center island with sink, black stone countertops, white appliances, a breakfast bar, an eat-in area and an adjacent dining space that flows easily into the great room. It is functional and full of personality, with room to reimagine if desired. The primary suite is spacious, offering slider access to the deck and a large bath with dual vanities, spa tub and walk-in shower, presenting an opportunity to update and personalize. Guest bedrooms are comfortably sized, and the guest bath is generous with dual vanities. An in-residence laundry room adds convenience. Outdoors, a caged pool with spa sits privately to the side of the home, while the rear of the property opens to excellent boating water. A private dock and boat lift are positioned along a protected canal, bordered by mangroves and just moments from Sarasota Bay. Located in The Bayou, an intimate gated enclave within Bay Isles, residents enjoy access to the private Bay Isles Beach Club, along with optional membership to the Longboat Key Golf & Tennis Country Club and Harbourside Moorings deepwater slips. This is a rare opportunity to enjoy waterfront living today, with the freedom to shape what comes next in one of Longboat Key’s most desirable communities.
