Welcome to Bay Island, ideally positioned on the north end of Siesta Key, where island living meets exceptional convenience. Just moments from Siesta Beach, Siesta Key Village, and downtown Sarasota's waterfront dining and cultural offerings-with easy access on and off the island-this elevated Key West-style residence is set across a rare double lot, an uncommon offering on Siesta Key. Fully renovated in late 2019, the home features new siding, roof, electrical, plumbing, irrigation, hurricane-rated windows and French doors, and two HVAC systems. It has since been further enhanced with premium retractable invisible screens on all French doors, kitchen and bath refinements, and a whole-house water filtration system, along with additional upgrades that reflect its continued care and quality. The open-concept floor plan is filled with natural light, highlighted by vaulted ceilings, LVP flooring, and a natural gas fireplace. Multiple covered terraces extend the living space outdoors, reinforcing the home's relaxed coastal design. The kitchen is designed for both everyday living and entertaining, centered around a large quartzite island with extensive drawer storage and pull-out shelving. A full Thermador appliance package includes a gas range, refrigerator and freezer columns, and dishwasher. Soft-close cabinetry and thoughtful storage solutions provide both function and efficiency. French doors open to an oversized covered deck overlooking mature tropical landscaping. The well-sized owner's suite is located on the main living level and includes a walk-in closet and a private en-suite bathroom featuring a double vanity and large walk-in shower. A den on this level offers flexibility and can easily serve as a fourth bedroom or home office. Upstairs, two generously sized guest bedrooms share a newly appointed bathroom and enjoy access to a third-level terrace ideal for sunset views. Outdoor living sets this property apart. The double lot creates an expansive backyard with a recently resurfaced pool, travertine decking, and multiple covered terraces-an uncommon offering on Siesta Key. The additional lot provides flexibility for future enhancements while preserving privacy and open space.
