Unique opportunity to own a high-security, earth-sheltered underground home with a massive barndominium addition on 4 acres in Hugo, OK! Located on a dead-end road, this energy-efficient property is built for durability with 1-foot thick walls and an 8-inch concrete roof. The main living area features a bright, open-concept kitchen and dining space with a large island and stainless steel sink. The primary suite offers a private retreat with his-and-her closets, dual sinks, and a dedicated office or flex space. The underground layout includes 2 spacious bedrooms, 2 full bathrooms, and 2 additional bonus rooms-ideal for a bunkroom, hobby space, or office. Ceiling fans are installed throughout for added comfort. The recently added 1,450 sq. ft. (more or less) barndominium expansion is filled with natural light from large windows and features an open-concept loft-perfect for additional bedrooms, a game room, or a second primary suite. An additional bathroom is already underway with plumbing and electrical in place. Major systems-including the roof, HVAC, and septic-are all approximately 2 years old, offering peace of mind. Outside, enjoy a true entertainer's setup with a covered patio and outdoor kitchen complete with refrigerator, sink, grills, and TV. The property also features a creek, circular driveway, hen house, two 25x40 shop buildings, and a productive mini-orchard with 20 paper shell pecan trees plus apple and peach trees. An on-site tiny home is negotiable. Fully spray-foamed and total electric (PSO) with Grant Public Water, this property offers privacy, security, and a versatile lifestyle with endless potential.
