This presentation initially took place at the 2020 Building Enclosure Symposium.
In the 1950s, American architect Frank Lloyd Wright developed a building system using concrete block components that could be assembled into a home, which he described as “Usonian Automatic.” In 1955, Wright designed such a home for Dr. Toufic Kalil and his wife, who built their home in Manchester, NH, with the assistance of a local contractor.
Wiss, Janney, Elstner Associates, Inc. (WJE) was selected by the heirs of the Toufic Kalil House to assess the existing conditions in preparation for selling the home. After WJE’s initial meeting, a landscape contractor demolished a site wall with his truck.
Based on our observations of existing conditions and research of historic documents, WJE developed repair documents to replicate the severely damaged site wall. The company also developed roofing repair and replacement documents to replace the leaking roofing system installed in 2003. Documents from the Frank Lloyd Wright Archives housed at the Avery Library of Columbia University supplemented the Kalil family’s personal papers.
The personal family records revealed names of products used for the original roofing system which differed from those in the project specifications. Little information was found about these products. The challenges of the existing conditions of the concrete roof deck and low flashing heights demanded creative approaches to the roofing replacement material and assembly.
