It is an "ABC" house. During WWII (and shortly after) the government built a large number of houses in Richland, WA - in order to provide housing for those who were involved in the Manhattan project. Each floor plan had a designated letter. Our particular plan is called an "R" house. A total of 146 "R" houses were built. "R" houses were commonly occupied by army officers with family. Our house was built in 1948.
