Architecture & history

Carroll Alsop House is a historic house located at 1907 A Avenue East in Oskaloosa, Iowa.It is one of seven Frank Lloyd Wright designed Usonian houses located in Iowa, and one of two that were constructed in Oskaloosa. Both were completed in 1951. This house is an L-plan, unless you count the carport, which makes it a T-plan. It was a custom-built house that embodied the ideals of "free and simple living, in touch with nature, for the family of moderate means."

In 1947, Frank Lloyd Wright was approached by two families from Oskaloosa, Iowa, who requested his architectural services for designing their homes. Wright accepted the commission, leading to the design of the Carroll Alsop house and the adjacent Lamberson house. The project was supervised by Wright's apprentice, John deKoven Hill, with construction managed by builder Jim De Reus.

The house was listed on the National Register of Historic Places on November 9, 1988.

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.
