Legacy on the St. Johns. Set on 3.5 acres with sweeping river frontage, this waterfront estate offers rare scale, privacy, and craftsmanship. The 4,068 SF main home opens through a columned portico into a 20' foyer and triple-arched gallery hall. A bow-windowed river room and study with gas fireplace and built-ins anchor the main level, alongside a chef's kitchen and master suite with double tray ceiling and spa bath. Elevator, 2025 roof, and windows throughout framing river views. Upstairs bonus room with morning kitchen and half bath offers flexible living. Screened pool and spa overlook the water; full dock package includes covered slip, boat lift, platform, and bulkhead. The 1,960 SF guest house with screened porch and two-car garage suits multigenerational living or extended stays. Minutes from Fleming Island's top schools, dining, and shopping -- privacy without isolation. Properties like this on the St. Johns rarely come to market.
