OK all you architectural sleuths time for the answer. Our AR Enhanced Intern team member, Isabella, took the prize with this answer: “Maybe since it’s so low and possibly on a flood plain near a river the holes might be meant for water and air to pass through.” Bingo. The key clue given was that this home was in Sacramento County, which lies in the flood plain of the Sacramento Delta watershed. So, like the home pictured in this post which was just down the street from the quiz home, homes to be built to survive a flood should the waters of the Delta ever breach the elaborate system of levies that the Army Core of Engineers have built. The “windows” on the quiz home are flood vents designed to open in case of a flood and relieve the force of flood water hydrostatic pressure that could cause structural damage or even sweep the house away. Congratulations Isabella!
