Sometimes you find a home and immediately feel the WOW factor! 18 Althea is one of those homes, nestled in the wooded marsh in the Fullerwood neighborhood of St. Augustine. Built on stilts, the 2,223 SF property sits on .67 of an acre, backing to Robinson Creek. Imagine taking your paddle board or kayak to the intracoastal waterway. The builder spared no detail, importing materials to create a serene retreat like no other. An extended paver driveway leads to a covered parking area and storage, perfect for vehicles, water toys and supplies. Upstairs, the wrap-around porch is welcoming with a bar for seating. Through the double doors, the open-concept great room/dining and kitchen combination is perfect for entertaining. High ceilings are covered in wood. The main floor of the house includes TWO primary suites with large closets and ''matching bathrooms,'' plus a third room with double doors, currently being shown as a bedroom (nonconforming). Stairs lead to a 250 SF loft that can be turned into another bedroom, office, or a hangout space. This property is zoned RS-2. Being close to Vilano Beach and the historic district of St. Augustine and the best shopping and restaurants the area has great benefits. NO HOA or CDD fees! This unique home won't last for long!
