Tucked within the exclusive gates of Barton Creek's Mirador Escala community, 3509 Lost Creek Blvd emerges as one of the most architecturally refined and secluded estates in all of Austin Real Estate. This 14,113-square-foot residence spans over 3.19 acres of manicured grounds and protected Hill Country vistas—delivering a rare blend of scale, sophistication, and tranquility just minutes from downtown Austin.

3509 Lost Creek Blvd – A Grand Reimagining of a Hill Country Estate

Originally built in 2003, this estate has undergone a meticulous reimagination from 2018 to 2023, transforming every inch into a timeless expression of luxury. The vision was guided by enduring materials and bespoke craftsmanship, from Venetian plaster walls and Presidio steel-framed windows to mesquite hardwood floors inlaid with ebony.

"The level of thought and artistry that went into this home is exceptional," said Bridget Ramey of Kuper Sotheby's International Realty, who represents the listing. "It's rare to find a property that combines privacy, design pedigree, and such a sense of serenity."

The estate's presence is immediately felt upon arrival. A gated entry leads to a long private drive and an imposing stucco façade finished in hand-applied LaHabra—signaling a level of quality typically reserved for custom estates in Beverly Hills or Montecito. But here in Texas Real Estate, it's a rare and distinguished find.

Elevated Interiors for Everyday Living and Entertaining

Inside 3509 Lost Creek Blvd, the two-story foyer sets a dramatic tone with a vintage chandelier, curved staircase, and soaring ceilings. Arched openings guide you into formal and informal living spaces, all designed to maximize light and landscape views.

The kitchen is a chef's dream, appointed with custom cabinetry, dual quartz islands, and top-tier Wolf and Sub-Zero appliances. This space flows effortlessly into the main living areas and outdoor terraces, creating an ideal setting for both quiet evenings and large-scale entertaining.

The owner's wing is a sanctuary in its own right, offering a see-through fireplace, dual dressing rooms, wet bar, and a spa-quality bath wrapped in Calcutta Gold marble. A steam room and fitness studio enhance the wellness experience, fully integrated into the home's design.

"Every detail has been curated not only for beauty but for lifestyle," said Ramey. "From the custom wine cellar to the infinity-edge pool, this home elevates the everyday."

Private Guest Living and Seamless Indoor-Outdoor Flow

A unique highlight of the estate is its secure guest quarters—fully outfitted with a separate entrance, private garage, kitchen, living area, and bedroom suite. Whether hosting long-term guests, extended family, or live-in staff, the layout ensures autonomy without sacrificing unity.
