Description

Welcome to The Fontaine House. Designed for the way life is meant to feel in the Florida Keys -- relaxed, connected, and effortlessly enjoyable -- this property offers comfort, flexibility, and thoughtful upgrades on a generous nearly 15,000 square foot parcel. The main residence features 3 bedrooms and 2 baths with a bright, open layout filled with natural light. The kitchen includes stainless appliances, a gas cooktop, and a wine bar that naturally becomes the gathering space for everyday living and entertaining. Indoor living flows outside to a screened, heated saltwater pool surrounded by tropical landscaping, creating a private setting for relaxation or hosting guests. A whole-house generator supported by a 500-gallon propane tank adds confidence and convenience. On the lower level of the main home, additional finished flex space with its own bathroom offers versatility that is hard to find -- ideal for a home office, gym, hobby area, or bonus living space. The detached two-story guest house, built in 2018, offers 2 bedrooms and 2 baths with quartz countertops, stainless appliances, and durable flooring, providing comfortable accommodations for extended family, guests, or flexible living arrangements. The oversized lot provides room to spread out, entertain, and enjoy outdoor living with privacy -- a true advantage in the Keys where space is often limited. Enjoy the ability to walk or bike to nearby schools and dining, with a boat ramp just minutes away and endless opportunities on the water -- from fishing and diving to sunset cruises, sandbar days, and exploring the surrounding waters that define the Keys lifestyle. Schedule your private showing to experience the layout, setting, and lifestyle for yourself. Buyer to verify all facts.
