Tucked privately among approximately 8 wooded acres in Shiloh, this remarkable estate offers nearly 6,200 square feet of living space plus a separate cottage, all on a mature homesite. This incredible location balances the feeling of a private luxury estate and a convenient location! The main residence offers 6 bedrooms and 5 bathrooms, including a finished walkout lower level with full kitchen, fireplace, bedroom, and full bath that could easily function as a private living suite or apartment. The primary suite features his and her closets and a beautifully remodeled spa-style bathroom with an expansive walk-in shower and large soaking tub. Extensive updates throughout the home include new flooring throughout the majority of the home, updated kitchen countertops, island, and fixtures, remodeled hall baths, remodeled basement bath, office built-ins, and an updated butler’s pantry. The massive oversized 3-car garage has extra depth to allow for additional storage or a large workshop area. Originally built with extraordinary attention to strength and efficiency, the home features metal stud framing with plaster applied over metal mesh on both the interior and exterior, creating a structure reminiscent of old-world masonry, or castle construction. This rare building method provides exceptional energy efficiency, sound insulation, durability, and fire resistance rarely found in residential homes today. Seller's electric bills are comparable to a home with much less square footage. Major system and exterior improvements include roof (2021), one HVAC system (2023), exterior paint, new concrete landscaping paths and patio to the front entry, extended parking pad, and a new private drive installed in 2024. The property also includes a detached cottage structure offering additional flexible-use space (think private office suite, art studio, stand-alone gym, potential pool house, partyroom, or extraordinary she-shed). This bonus building has been extensively renovated with new flooring, updated bath fixtures, new kitchen cabinets, countertops and appliances, wall treatments, mini-split HVAC, and gutters, offering exceptional flexibility for a variety of uses. Buyers are encouraged to verify permitted uses directly with the Village. This incredible property is nestled within the highly regarded Shiloh Village School District 85 and O'Fallon Township High School District 203. Conveniently located near Interstate 64, Scott Air Force Base, and about 25 minutes to St. Louis, providing easy access to the metro area. Located in the Country Estate zoning district, the property may also offer potential for horses or hobby farming, subject to verification of regulations with the Village of Shiloh. Don't miss this unique opportunity. Properties offering this combination of space, construction quality, and location are rarely available in the Metro- East!
