About this property

Casa Tortuga — a bold architectural statement in Austin’s coveted 78704 — channels the spirit of Mexico City’s Luis Barragan, with its sculptural form, interplay of light, and seamless connection to the outdoors. Built of reinforced concrete and later reimagined with warm, earthy textures, this residence is both sanctuary and showpiece. Minutes from downtown Austin, you’re steps from South Congress, Lady Bird Lake, and the city’s best dining, music, and culture — yet your home feels like a private retreat. Inside, sunlight filters through expansive windows, softening modern lines and framing a lush canopy of trees. The open-concept main level — kitchen, dining, and living — is crafted for effortless daily living and memorable gatherings. Whether it’s morning coffee, a jog along Lady Bird Lake, or an evening under the skyline, Casa Tortuga adapts effortlessly to the rhythm of Austin living. With 2 bedrooms and 2.5 baths, it embraces a true lock-and-leave lifestyle ideal for globe-trotters, bachelors, and empty-nesters alike. The crown jewel: a newly completed third-story rooftop terrace with panoramic downtown views. A private spa awaits under the Texas sky, paired with a covered dining area and lounge deck. By day, it’s a sun-soaked retreat; by night, an intimate, lantern-lit escape worthy of Mexico City. In addition to its architectural pedigree and premier location, Casa Tortuga has also shown strong performance as a short-term rental when selectively offered. From January through May 2025, it hosted 25 bookings across 70 nights, generating over $36,000 with an average nightly rate above $525 — despite significant owner use during peak periods. This flexible model suits those who want to enjoy the home personally while keeping an option for occasional guest stays. Casa Tortuga is more than a home — it’s an experience in design, location, and lifestyle, offering a rare blend of urban proximity, architectural artistry, and versatile ownership potential.
