About this home
600 3rd Ave S #406 is a 2025-built home in Castille Urbana Condo, St Petersburg. Inside you'll find 3 bedrooms, 3 bathrooms, and 1,650 square feet of living space. Listed at $975,000 (about $591/sqft), 68 days on market. Flood zone X - outside the FEMA high-risk areas, which keeps insurance manageable. HOA runs $579.26 monthly.
Never lived in and offered directly from the developer, Residence 406 is a fourth-floor corner residence within Castille Urbana, offering a fresh opportunity to own in one of downtown St. Petersburg’s newer boutique condominium buildings. An Exclusive Developer Incentive, offered directly by the developer, provides meaningful value toward the purchase and creates a compelling alternative to the current resale inventory. Positioned on the southeast corner, the residence benefits from eastern light and a private balcony that extends the living space outdoors. Expansive impact-rated windows and 9-foot ceilings create a bright, open feel, complemented by engineered hardwood flooring, 8-foot interior doors and generous walk-in closets. The kitchen is finished with Bosch stainless steel appliances, quartz countertops, solid wood soft-close cabinetry, under-cabinet lighting and designer glass pendants over the island. A full-size washer and dryer, abundant storage and low-maintenance Trex balcony flooring add to the ease of everyday living. Castille Urbana is home to just 40 residences and offers assigned parking within a gated garage, controlled lobby access, a resident lounge, fitness area, bike storage, dog run, and outdoor gathering space. Its boutique scale also allows for comparatively low monthly association fees for newer downtown condominium living. Located in Flood Zone X and close to Central Avenue, restaurants, cafés, museums, waterfront parks and the St. Pete Pier, the location makes it easy to enjoy downtown while coming home to a quieter residential setting.
