Home description

Lot 80 - The Topaz combines timeless Low Country charm with modern comfort in a thoughtfully designed 4-bedroom, 3.5-bath layout with a spacious 3-car garage. The welcoming foyer opens to an airy great room that flows into the dining area and extended covered lanai, creating a bright, open space for entertaining or everyday living. The chef-inspired kitchen features a large island, morning kitchen, and walk-in pantry. Tucked at the rear, the owner's suite offers a peaceful retreat, while two secondary bedrooms share a private hallway. A fourth bedroom with garage entry adds flexibility for guests or multigenerational living. A study in lieu of a flex room provides a private office or creative space. Bath 2's shower in lieu of a tub adds a spa-like touch. RiverTown, along the St. Johns River, offers parks, lakes, preserves, and scenic trails for active Northeast Florida living.
