8181 Douglas Avenue PH 9-12 An extraordinary four-level penthouse spanning floors 9–12 in the heart of University Park, crowns a gated boutique building that includes 14 other luxury residences. Conceived and built over multiple decades as a vertical estate, the home offers 5 bedrooms, 6 full baths and 7 half baths, with all levels connected by striking staircases and a private internal elevator. Designed for both elevated daily living and grand-scale entertaining, there are multiple living and dining spaces supported by five kitchens, including a full industrial catering kitchen. The owner’s level on its own complete floor is a retreat with separate living and dining areas, a kitchen, bar, and expansive custom baths and dressing rooms. Other amenities include a private gym, wine room, rooftop terrace, staff quarters, a dedicated office for a house manager and security and 12 parking spaces. Advanced security features and discreet access points provide a level of privacy and protection rarely achieved in residential design - a sanctuary in the sky. Throughout, the home evokes the ambiance of a refined European boutique hotel or a residence in one of Europe’s most fashionable metropolitan centers - Paris, Monte Carlo, Vienna, and beyond - while reflecting the sophistication of NYC's most distinguished homes. It ultimately establishes its own benchmark as a singular expression defined by uncompromising scale, craftsmanship, and presence. Residences of this caliber are exceedingly rare, offering a level of design and livability more often found in the world’s great private homes than in vertical living. This is not simply luxury - it is a new, unprecedented standard of secure, private living, intentionally crafted for those who value discretion, permanence, and an elevated way of life. With the scale, privacy, and gravitas of a standalone estate paired with the convenience and security of a luxury building, this is a truly exceptional offering in one of Dallas’ most prestigious neighborhoods.
