About This Home

4100 Mcbrine Pl

A home where craftsmanship meets calm — The Harmony House is a rare, ground-up transformation in the heart of Westlake. Taken completely down to the studs and rebuilt by Kopfer Taylor Interiors, every inch has been 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 a lush landscape of curated greenery, opening to a private courtyard framed by gardens and a tranquil fish pond water feature — setting the tone for the calm and sophistication found 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 dedicated wellness suite that includes a gym, sauna, and full air and water filtration systems. The primary suite is a haven of its own, 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 includes its own en-suite bath, and a detached studio with a full kitchen and half-bath offers a flexible living space. With plumbing already in place, it can be easily converted into a full 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, vast green lawn, lounge areas, and a covered outdoor fireplace — the kind of space that turns everyday moments into lifelong memories. Located within the award-winning Eanes ISD, just minutes from downtown Austin, The Harmony House is a once-in-a-lifetime opportunity to own a private, design-driven estate in one of the city’s most desirable enclaves.
