“Harmony House”: A $5 Million Architectural Sanctuary in Texas
At a time when luxury buyers are increasingly drawn to homes that offer privacy, wellness, and architectural substance, 4590 County Road 340 emerges as a rare expression of intentional living. Priced at $5 million, the newly built estate sits on more than two wooded acres in McKinney, delivering a modern retreat that feels worlds away from the pace of the city—yet remains within easy reach of Dallas.
Completed in 2025 after more than a decade of planning and design, the residence spans 5,347 square feet and includes five bedrooms and seven bathrooms. Known as “Harmony House,” the property was conceived as a sanctuary that integrates architecture with nature, reflecting principles inspired by Frank Lloyd Wright’s philosophy of organic design.
Architecture Designed to Restore Balance
From the moment one turns onto the winding road leading to 4590 County Road 340, the experience feels deliberately choreographed. The approach passes a stream, mature trees, and a nearby winery before opening onto a gated private drive. The estate itself is nestled within rolling terrain dotted with more than 400 trees, creating a setting that prioritizes tranquility and seclusion.
“This home was designed to be restorative,” said listing agent Janelle Alcantara of Briggs Freeman Sotheby’s International Realty in a conversation with Luxury Houses Magazine. “The owner wanted a place where architecture and landscape work together to create calm, not distraction.”
Built using a refined mix of stone, concrete, wood, and steel, the contemporary structure features expansive glazing that frames forest views in nearly every room. Natural light and the sights and sounds of the surrounding woodland are integral to the experience, reinforcing the home’s connection to its environment.

Interiors That Blur the Line Between Home and Retreat
Inside 4590 County Road 340, the floor plan is intentionally flexible, extending beyond traditional single-family living. Three distinct living areas, two kitchens, and multiple multifunctional rooms allow the home to adapt easily for entertaining, extended stays, or work-from-home living. Concrete and wood flooring, sculptural lighting, and two fireplaces add warmth and texture to the modern interior palette.
“The layout was designed for real life, not just visual impact,” Alcantara told Luxury Houses Magazine. “It can host large gatherings effortlessly, but it also feels incredibly intimate when it’s just family.”
The primary suite, located on the main level, includes a fireplace, spa-style bath, and serene views of the wooded grounds. Throughout the home, thoughtful amenities—from commercial-grade appliances to smart technology—underscore its position at the upper tier of McKinney Real Estate, where newly built architectural homes of this scale are increasingly scarce.

Outdoor Living Framed by Forest and Sky
Beyond the walls of the home, the estate unfolds as a private nature preserve. A winding trail leads through the trees to an outdoor cinema, al fresco dining area, and a sunset viewing perch designed to capture the changing light at day’s end. A resort-style pool and outdoor living spaces further enhance the sense that this is not merely a residence, but a destination.
“There’s a strong emotional response when people walk the property,” said Alcantara. “Buyers often tell us it feels like a luxury vacation retreat they never have to leave.”
The land also offers future potential, with clearings suitable for guest cabins or creative studios—an uncommon feature that adds long-term value within both McKinney Real Estate and the broader Texas Real Estate landscape.

Market Context and Investment Appeal
Public records show the land last traded in 2022, prior to the construction of the current residence. Its 2025 debut at $5 million reflects not only the quality of the build, but also the growing demand for private, design-forward estates north of Dallas. Proximity to McKinney’s dining, shopping, and cultural offerings, as well as access to the emerging TKI Airport, further strengthens its appeal within Texas Real Estate.
According to the listing team, private tours are reserved for qualified buyers, reinforcing the home’s position as a discreet offering for a discerning audience.
