A one-of-a-kind custom home on RiverTown's Main Street, with a detached guest apartment, courtyard entertaining area and sweeping waterfront views. Southern Grace, Custom Craftsmanship: 305 Sternwheel Dr is the only home in all of RiverTown built by custom builder Cornerstone Homes, set apart on the quaint Main Street section of the community. The architecture carries Southern style: deep front porch, gracious proportions, and a floor plan built for both everyday living and entertaining. This home has been meticulously maintained, with a newer roof, a new gas water heater, newer AC units, and brand-new wood flooring across the main level. Every major system has been addressed, so the next owner starts with peace of mind, not a punch list. From the front porch and upstairs balcony, the water views stretch out and change with the light throughout the day. The primary suite has its own private balcony, a quiet spot for morning coffee or watching the sun set over the water. Don't worry about the stairs - the main house was built with an elevator shaft, perfect for aging in place! Few homes in RiverTown offer this: a fully detached guest house above the garage, connected to the main home by an open-air courtyard. The guest house (ADU) is a complete apartment with its own bedroom, bathroom, and mini kitchen, ideal for multigenerational living, a mother-in-law suite, long-term guests, or private home office and studio. It's the kind of flexible living space buyers search for and rarely find in this community. Life on RiverTown's Main Street RiverTown is a riverfront, master-planned community along the St. Johns River in northwest St. Johns County, and the Main Street section places this home within walking distance of the neighborhood's daily rhythm. Residents have access to three amenity centers, including the RiverClub on the St. Johns River with an oasis-style pool, waterfront dining, fishing pier, kayak and paddleboard launch, amphitheater, game room, and riverside boardwalk. Miles of nature trails and sidewalks connect parks, wetlands, and preserves, along with a dog park, biergarten, and event lawn. Boating and fishing access to the St. Johns River is part of everyday life here. Location: An Easy Commute Between Jacksonville and St. Augustine RiverTown sits near State Road 13 and Longleaf Pine Parkway, with access to I-95 and CR-210, putting both Jacksonville and Historic Downtown St. Augustine within a comfortable drive. St. Johns County's more than 60 miles of Atlantic beaches, from Ponte Vedra Beach to St. Augustine Beach, are also accessible for a day on the sand. Schools in St. Johns County St. Johns County School District is consistently ranked among the top-performing districts in Florida. RiverTown has historically been zoned for Freedom Crossing Academy (K-8) and Bartram Trail High School, though attendance boundaries have changed in recent years. Buyers should confirm current zoning directly through the St. Johns County School District's attendance zone locator prior to closing. The Bottom Line 305 Sternwheel Dr pairs a custom-built, well-maintained Southern-style home with a feature that's genuinely rare in RiverTown: a private, fully equipped guest apartment across a courtyard from the main house. Add river views from two levels, resort-style amenities, top-ranked St. Johns County schools, and an easy commute to Jacksonville and St. Augustine, and this is a home built for how people want to live in RiverTown.
