Allison Henry Dean (1897-1990) was a writer, realtor, and builder/architect in Portland, Oregon. His mid-century modern houses were ahead of their time and are known for open floor plans, vaulted ceilings, large windows that bring the outside in, built-ins and storage galore.
According to PortlandModern.com, “Dean seemed an interesting personage. He was a real estate agent and developer who seemed to be forward looking in many ways … did some other small houses using minimal construction techniques with a mid-century modern flavor, and it appears he handled a resale of the Jan De Graf house which is Portland’s only home designed by Richard Neutra (Van Evera Bailey was the local supervising architect for the project). Dean was an amateur actor active in the Portland theater scene and also a writer.”
Born in Scituate Harbor, Massachusetts in 1897, Dean grew up in Southern Saskatchewan, where he helped build his first house at the age of 14 on his father’s pioneer homestead. After serving in the Canadian Royal Air Force from 1917-1919, he moved in Portland in the mid-1920s, where he designed and built “Chassis United Houses” and “dozens of conventional homes ranging in value from $3500 to $20,000.”
By the early 1940s Dean was a charter member of the National Association of Home Builders, a guest lecturer on Real Estate at the University of Oregon, and traveled to Washington D.C. to served as consultant to the U.S. Government’s Housing Agency. In 1944 he published “Low Cost Homes for Millions: Dream of Possibility,” a 16-page booklet outlining how prefabricated, factory-built homes “invented, designed, and tested by Allison H. Dean” could be the solution for affordable housing for “every shop girl, every young couple, every old couple.”
This website is a collection of houses he built primarily in the Southwest Hills of Portland in the 1950s and 1960s, along with other collected writings as they become available. The site’s curator, Corinna Buchholz, lives with her family in a 1969 Allison-Dean built home on Patton Court.

I’ve found a home at 2738 SW Patton Ct with original permits that state it was done by Allison Dean. Do you have any other information on this home?

Not much on that house specifically, but that whole cul-de-sac has several Dean homes built around the same time (1969 or so). Looking through other photographs and comparing them to the 2738 house you might be able to identify Dean-specific traits such as multiple fireplaces, house built on a steep slope with entry on the top floor, etc. Is it going on the market soon?

Yes, the above description matches this home perfectly. It’s a day ranch built in 1957 that is built on a slope with 2 large fireplaces. It will be on the market in about 3 weeks.

I remember your grandfather well. He and Mrs. Dean were such wonderful people. She would fix Welsh Rarebit souffle for a “meal” after our High School Sunday evening meetings at their home in Northeast Portland before moving to the Springs. There used to be a picture he painted on the wall at Kirk’s place on Mason. Is it still there. Ioved it.
