About This Property
Imagine that your drive home is one of the highlights of your day. While others endure the stress of their commute, you veer off the main thoroughfares towards a home that was created to restore balance and harmony in life. A home so intentional that it's taken more than a decade to realize. Welcome to "Harmony House." An elite sanctuary that integrates masterful architecture with the beauty of nature. Only 45 minutes from the heart of Dallas, a winding road ventures through the trees, alongside a stream and past a quaint winery. This evokes a sense of rejuvenation expected from a luxury vacation retreat. Entering the private drive to your 2 acre, heavily wooded estate, you are reminded that THIS is what you've worked for. Inspired by the philosophies of Frank Lloyd Wright, this architectural gem captures the essence of nature in every room. It indulges the senses with the healing sounds, scents and imagery of the forest; while offering the sophisticated amenities of an architect designed modern home. The gentle rolling terrain is home to more than 400 trees. A private nature trail winds through the trees to an outdoor cinema, dining area and sunset viewing perch. There are clearings in the woods for future cabins to be constructed to enhance the lifestyle of the residents. Inside, the floor plan offers flexibility beyond single family living. Whether used as a primary residence or a luxury vacation home, the property offers exquisite entertaining spaces, serene bedroom suites and multi-functional spaces that provide an array of uses. There are 3 living areas, 2 kitchens, 2 offices and a storm shelter. The house is prepped for an elevator & wine cellar. Proximity to the new TKI Airport, makes this a valuable proposition for a family investment. Experience this property, created by an award winning design team: Private tours given to buyers with proof of funds. Semi private tours arranged monthly for up to 10 prospects.
