Roald Gundersen, an architect, and his life and business partner, Amelia Baxter, 31, with their two children, 3-year-old Estella and 9-month-old Cameron.
Mr. Gundersen, who founded Gundersen Design in 1991 and built his first house in the forest 10 miles east of the Mississippi River and 150 miles northwest of Madison two years later, has made a career of working with trees.
Mr. Gundersen built his home and greenhouse using whole trees for structure and support, after first pruning and bending them.
After finishing the A-frame, Mr. Gundersen built a 100-by-20-foot solar greenhouse next door with thick straw-bale walls on three sides, banked into the north slope.
The small house attached to the greenhouse was constructed out of elm trees peeled of their bark.
