About this home

AUCTION BIDDING OPEN: Bidding ends August 15th. Previously Listed $5M. Current High Bid $2.475M. Showings Thursday - Sunday 1-4pm, and Daily By Appt. Earn an incentive by 4 August. Harmony House is a sanctuary a decade in the making, where masterful architecture meets the restorative power of nature. Only 45 minutes from downtown Dallas, a winding road passes a stream and a quaint winery en route to this heavily wooded, 2.02-acre estate. Inspired by the philosophies of Frank Lloyd Wright, the modern residence captures the essence of the forest in every room, pairing healing natural imagery with sophisticated, architect-designed amenities. Rolling terrain holds more than 200 trees and a .28-mile private trail leading to a future cinema site, dining area, and sunset viewing perch, with clearings reserved for future cabins. Flexible interiors—including multiple kitchens and offices—suit a primary residence or retreat, with proximity to the new TKI Airport adding investment appeal.
