At Taliesin, Frank Lloyd Wright’s studio near Spring Green, Wis., an eager band of draftsmen once gathered to work alongside the much-revered architect. One of those apprentices, known then as “the pencil in Wright’s hand,” was a young architect named John Howe. Howe, an original member of the Taliesin Fellowship Associated Architects, later built a cottage across a wide valley from Taliesin. As the story goes, one day in the late 1950s, a young couple from the Twin Cities saw a picture of that cottage and wrote to Howe, asking him to design a house for them and their two young boys on a wooded hillside overlooking Lake Minnetonka in Orono. Howe delivered with a sprawling, 3,620-square-foot Prairie-style house, known as Wintertree, that’s now on the market for $2.295 million.
