About This Property

A home where craftsmanship meets calm - The Harmony House is a rare, ground-up transformation in the heart of Westlake. Taken to the studs and rebuilt by Kopfer Taylor Interiors, every inch is thoughtfully curated to create a residence that's as timeless as it is livable. French contemporary in influence, with organic finishes and a serene flow, this is design in its highest form - quiet, intentional, and deeply luxurious.

From the moment you arrive, the experience is unforgettable. Limestone steps lead through lush greenery to a private courtyard framed by gardens and a tranquil fish pond - setting the tone for the calm and sophistication within.

Set on a flat, one-acre lot in one of Austin's most coveted neighborhoods, this five-bedroom, five-and-a-half-bath estate feels like a private retreat. White oak floors, cut limestone walls, custom steel accents, and a striking Calacatta Paonazzo island create a palette that is both refined and inviting. The layout is tailored for modern family life - with open gathering spaces, a sculptural bar and lounge, and a wellness suite including a gym, sauna, and full air and water filtration.

The primary suite is a haven, with dual baths and closets, a steam shower, private courtyard access, and thoughtful luxuries like unlacquered brass fixtures and built-in dry-cleaning care. Every secondary bedroom has its own en-suite bath, and a detached studio with full kitchen and half-bath offers flexible living space. Plumbing is in place to convert it into a guest apartment.

But it's the backyard that truly takes your breath away.

Flat, fenced, and flawlessly designed, it features a saltwater pool, sport court, lawn, lounge areas, and a covered outdoor fireplace - the kind of space that turns everyday moments into lifelong memories.

Located in award-winning Eanes ISD, just minutes from downtown Austin, The Harmony House is a rare chance to own a private, design-driven estate in one of the city's most desirable enclaves.
