Description

5 Bedrooms | Guest House | Nearly 15,000 Sq Ft Lot | Tavernier, Florida Keys Welcome to The Fontaine House at 155 Fontaine Dr -- a rare opportunity offering space, flexibility, and a layout designed for real life. With a total of 5 bedrooms across a main residence and a detached guest house, this property stands out in a market where additional living space is hard to find. The main home features 3 bedrooms and 2 baths with a bright, open layout filled with natural light. The kitchen is designed for everyday living and gathering, complete with stainless appliances, a gas cooktop, and a wine bar that naturally becomes the center of the home. Living spaces transition seamlessly outdoors to a screened, heated saltwater pool surrounded by tropical landscaping, creating a private setting for relaxing or entertaining. A generator with a 500-gallon propane tank adds peace of mind, while the finished lower-level flex space with its own bathroom offers versatility for a home office/gym. The detached two-story guest house, built in 2018, includes 2 bedrooms and 2 baths with quartz countertops, stainless appliances, and durable finishes -- ideal for extended family, guests, or a private separate living space. Set on a nearly 15,000 square foot lot in Tavernier, this property provides room to spread out, entertain, and enjoy outdoor living -- a true advantage in the Florida Keys. Located near local schools, dining, and everyday conveniences, with a nearby boat ramp providing quick access to fishing, diving, and exploring the surrounding waters, this home offers the lifestyle people move to the Keys for. If you've been searching for a home in Tavernier or the Upper Florida Keys with a guest house, larger lot, and flexible living options, 155 Fontaine Dr delivers a combination that is increasingly hard to find. Schedule your private showing to experience it in person. Buyer to verify all facts.
