Architecture & history

The Robert H. Sunday House is located in Marshalltown, Iowa, United States. It was designed by Frank Lloyd Wright in the Usonian style, and was listed on the National Register of Historic Places in 1988. Initially the Sundays choose the Usonian Automatic, a natural concrete block model, for their home. When it provided unworkable, Wright sent the plans for this house. In style and materials it is very similar to the 1953 Usonian Exhibition House. It was the sixth of seven houses designed by Wright and built in this style in Iowa. Sunday, who owned Marshall Lumber in Marshalltown, acted as his own general contractor. In fact, he and his wife did much of the work themselves. It is also believed to be last of this style built in brick. John H. "Jack" Howe, a Wright assistant who supervised the initial construction, designed an addition to this house in 1970 that conforms seamlessly with the original. It includes the family room, family room terrace, and the dining room. The original house followed an L-shaped plan, and with the addition it is now a T-shaped plan. Howe had previously designed (1964) the building for Sunday's business.

This atlas combines the Avery architectural drawing inventory with a published building index. Individual profiles link to their references. An archive record does not, on its own, establish that a building was constructed. Unknown construction dates and missing photographs are marked explicitly; unbuilt schemes are never presented as completed buildings.

Longer reference overviews and building-index material are adapted from Wikipedia contributors under CC BY-SA 4.0. Each photograph has its own creator, source and reuse licence. Restricted architectural drawings are linked to their archive rather than reproduced.
