Hillside Home School I, Educational building in Wyoming, Wisconsin

Hillside Home School I, also called the Home Building, was a Shingle Style structure designed by Frank Lloyd Wright in 1887 for his aunts Ellen and Jane Lloyd Jones. It served as a dormitory and library for their coeducational boarding school, with parlors, dining rooms, living rooms, kitchens and twenty-two rooms for girls and teachers. Wright had it demolished in 1950.

Frank Lloyd Wright designed this structure in 1887 when he was just 19 years old for his aunts to establish their school. The building served the institution until 1915 and was demolished in 1950 during campus modifications.

The 1907 Weekly Home News described the Home Building's parlors, one holding a carved fireplace that drew visitors' attention, plus dining rooms, living rooms and kitchens, and twenty-two large, sunny rooms for girls and some teachers. The paper called its architecture English, a nod to the Shingle Style Wright took from Joseph Lyman Silsbee.

The Home Building's site lies within the Taliesin estate, owned by the Frank Lloyd Wright Foundation, so access to the former campus is arranged through the estate rather than freely entered. The 1901 Hillside Home School building and the Romeo and Juliet Windmill still stand nearby, giving visitors the surviving Wright structures to look for.

Wright had already begun remodeling the Home Building in the early years of the Taliesin Fellowship, reconfiguring its roof and adding red tile to match his other Hillside buildings. He then ordered it demolished in 1950 while he was in England, so the site was cleared before his return, surprising apprentices such as Curtis Besinger.
