About This Home

3900 N County Line Road

Privately held since its original construction, this extraordinary architect designed retreat offers a rare opportunity to own the personal residence of the architect who envisioned and created it. Nestled on approximately 17.85 acres of rolling countryside, mature trees, ponds, and wildlife preserve, the property was thoughtfully designed to exist in harmony with its natural surroundings. The result is a home that feels less like a residence and more like a private mountain lodge retreat. Inside, craftsmanship and architectural character take center stage. Vaulted ceilings, exposed timber beams, reclaimed pre statehood tin, native stonework, knotty alder wood detailing, and walls of windows create an atmosphere that is both dramatic and inviting while framing the beauty of the landscape beyond. The home features 4 bedrooms, expansive gathering spaces, an upstairs bonus room, and a luxurious primary suite complete with a sitting area, fireplace, coffee bar, spa inspired bath, and oversized walk in closet. The outdoor living experience is a natural extension of the home. Expansive covered patios overlook a breathtaking koi pond with cascading waterfalls, a winding rock lined stream, and lush landscaping that create an atmosphere of complete serenity. Beyond the immediate grounds, wooded trails, open clearings, additional pond access, and abundant wildlife invite exploration and connection with nature. A 40' x 30' shop provides additional flexibility for hobbies, equipment, or workshop space. While the setting feels worlds away from the pace of everyday life, downtown Oklahoma City is approximately 25 minutes away, offering a rare balance of privacy and convenience. Properties with this level of architectural originality, natural beauty, and seclusion rarely become available. This is more than a home. It is a destination, a retreat, and a legacy property unlike anything else on the market. Schedule your private tour today.
