A once-in-a-generation opportunity in the heart of 78704. Set on an extraordinary half-acre lot—one of the largest residential lots available in Austin’s most sought-after zip code—3403 Winfield offers a rare combination of land, location, and limitless potential. Whether you’re looking to renovate and restore the existing mid-century ranch or create a legacy property from the ground up, opportunities like this are becoming increasingly scarce. The sprawling, tree-filled homesite provides endless possibilities, including the potential to build up to three residences (buyer to verify), making this an exceptional opportunity for builders, developers, investors, or those seeking an oversized estate lot in the urban core. Located in the highly acclaimed Zilker Elementary attendance zone, the property is just minutes from Downtown Austin, Zilker Park, Barton Springs, the Barton Creek Greenbelt, South Lamar, and South Congress. Despite its central location, the setting feels private, peaceful, and removed from the city’s hustle. The existing home offers classic mid-century charm and is ready for a thoughtful renovation, while major improvements already completed include a new HVAC system and insulation (2024), new electrical panel and meter box (2022), and roof replacement (2020). Large lots in 78704 are rare. Half-acre lots are almost unheard of. Whether your vision is a dream home, a family compound, or a multi-home development opportunity, 3403 Winfield is a property with exceptional upside in one of Austin’s most desirable neighborhoods.
