The cottage is specifically modeled after Wright’s 1950s Seth Peterson cottage, which is located on Mirror Lake near Reedsburg, Wis. Joe said he’s been to a lot of buildings designed by Wright throughout the years, but it wasn’t until Kelly stayed at the Seth Peterson cottage a few years ago that the couple decided to create their own version. “What we thought would only take a year ended up taking two and a half years,” Joe said. Wright began designing the Seth Peterson cottage for Peterson and his fiancé. Peterson, who shared a birthday with Wright, was a longtime fan of the architect. However, both men died before the cottage was complete, and others finished the structure years later. Joe said it was one of the last buildings Wright designed.
