At the age of 38, Frank Lloyd Wright accepted a commission from his oldest client to date for the design of a home in Highland Park. In 2010 the current owners purchased the house and began a 3-year restoration project. The work involved the structural reinforcing of the sagging second floor over the living room, roof framing, foundation repairs and replacement, and all new mechanical, electrical and plumbing. The kitchen and bathrooms were updated, and the former servants bedroom was converted to a new primary bath and closet. A top coat of stucco mixed to match the original color with integral color was applied to unify the exterior of the house. With an eye towards sustainability, the house was provided with ample attic insulation and exterior walls were filled with cellulose insulation. A geothermal heating and cooling system was installed and kept to a minimum through the use of extensive insulation and the fabrication of insulating glass interior storm windows.
