12 Danforth Rd is one of the Midwest's most stunning estates, with breathtaking views of The Great River Road and Mississippi River. Originally built in 1927, the home has had thoughtful updates made over time, with major renovations completed in 2013, including an underground tunnel connecting the main residence to the guest house and 11-car garage. The 7 bedrooms each offer private suite features. Located approximately 35 minutes from Lambert International, and 15 minutes from a private airstrip, the estate offers convenient transportation options. The charming towns of Alton and nearby Grafton provide marina access to major waterways. The residence, its systems and grounds have been meticulously cared for. Known as the "Olin Mansion," this exquisite property has approximately 15,000 sq.ft. of space in the main residence, and is situated on 32 acres of land in the Fairmont subdivision, a private development. We invite you to reach out to learn more about this remarkable estate.
