Agent Description

New Price | 5 Bedrooms | Guest House | Nearly 15,000 Sq Ft Lot | Tavernier, Florida Keys More space. More flexibility. More opportunity. Welcome to The Fontaine House-- a rare Upper Keys property offering a combination that's becoming increasingly difficult to find: a main home, detached guest house, pool, and nearly 15,000 square feet of land.

With 5 total bedrooms, this property was designed for real life--hosting family, welcoming guests, creating separation, working from home, or simply having room to spread out. The main residence features 3 bedrooms and 2 baths with a bright open layout centered around a kitchen built for gathering, complete with stainless appliances, gas cooktop, and wine bar.

Step outside to a screened, heated saltwater pool surrounded by tropical landscaping that creates a private setting to relax and entertain. Need flexibility? A finished lower-level space with its own bathroom works beautifully as a home office, gym, or bonus space, while the whole-home generator with a 500-gallon propane tank adds peace of mind.

Built in 2018, the detached 2-bedroom, 2-bath guest house offers quartz countertops, stainless appliances, and comfortable separate living. Located near schools, dining, everyday conveniences, and a nearby boat ramp for easy access to time on the water. If your Florida Keys wish list includes space, guest accommodations, and room to live beyond the ordinary--The Fontaine House is ready to be experienced in person. Buyer to verify all facts. Easy to Show!
