The house was originally constructed by famous local builder Earl Young, who was known for his whimsical, fairytale-like stone cottages that have been referred to as "mushroom houses," and even "Hobbit homes."
Located on 304 Park Avenue, the Thatch House was where Young lived up until the late 1940s with his wife and their children, per the Charlevoix Earl Young District report.
"This happened to be the house that Young built for himself when he was 20," Seitz, a mechanical engineer, told Insider.
This is the first time that Seitz is putting the house up for sale since he bought it in 2013, per listing records.
