Description
Nestled on over 12 private acres of rolling hills and lush greenery, this sprawling country estate offers the perfect blend of luxury, comfort, and tranquility. At its heart stands a majestic traditional full-brick home, with stately architecture that effortlessly combines classic charm and modern elegance. The expansive residence features multiple levels, including six bedrooms, two of which are primary suites, a gourmet kitchen, gorgeous family spaces, an indoor pool, a theatre room, and a walk-out lower level that opens to the beautifully landscaped grounds and a hot tub. The large windows allow for sweeping views of the property, flooding the interior with natural light.
Outside, the estate is a true oasis. A sparkling in-ground pool, surrounded by stone patios and manicured gardens, provides a peaceful retreat. Just beyond the pool, a charming pool house offers a cozy space for relaxation or entertaining, with ample room for guests to enjoy the serene surroundings.
A picturesque pond adds a touch of whimsy to the landscape, reflecting the beauty of the surrounding trees and rolling fields. The gentle sounds of nature provide a soothing atmosphere, perfect for moments of quiet reflection. An additional outbuilding, versatile in use, offers ample storage or space for hobbies, a workshop, or a potential studio. The entire property is enveloped in privacy, offering a peaceful escape from the hustle and bustle of everyday life, all within minutes of downtown O'Fallon. With its expansive grounds, luxurious amenities, and unparalleled serenity, this estate is a rare gem that promises an extraordinary lifestyle in a breathtaking natural setting.
