Welcome to 5801 Harrington Cove, a beautifully updated single-story home tucked away on a quiet cul-de-sac in The Courtyard, one of Austin's most sought-after lake communities. This home has undergone extensive improvements, including an expanded living room, added square footage, updated windows, beautifully refinished hardwood floors, and numerous thoughtful updates throughout. A complete HVAC system was newly installed in May 2026 through the Austin Energy Conservation & HVAC Program, including insulated ductwork, added insulation, a new air conditioning system, and furnace for enhanced comfort and energy efficiency. Designed for both everyday living and effortless entertaining, the spacious floor plan offers abundant natural light, enhanced by multiple skylights, generous living spaces, and the convenience of true single-story living. An energy-efficient gas log fireplace adds warmth, ambiance, and a reliable secondary heat source, while the home is generator-ready with electrical infrastructure in place for easy connection to a backup generator. Residents of The Courtyard enjoy access to a private lakeside community park along Bull Creek with walking trails, picnic areas, a day dock, and waterfront recreation. This is a rare opportunity to own a substantially updated one-story home in an established neighborhood where properties rarely become available.
