The Alice and Jack Lamberson House, also known as the Peter Maunu and Irmi Maunu-Kocian house, is a historic residence located in Oskaloosa, Iowa, United States. It is one of seven Frank Lloyd Wright-designed Usonian houses located in Iowa, and one of two that were constructed in Oskaloosa.[1] Both were completed in 1951. The Lamberson house is unique from the other Iowa Usonians for its extensive use of 60º and 120º angles. It features a low, sweeping pitched roof that makes the house look deceptively large, yet it is the second smallest of Iowa's Usonians.[1] It was listed on the National Register of Historic Places in 1988.
