I'm interested in the gene bank of how Americans have built in different regions in different times.
Good buildings make and are made by their settings, and they are appropriately different in different locations. Climate, culture, topography and materials have helped create regional architectural languages that seem curiously right for their locations and for all times.
I spent a lot of time on farms when I was growing up, and I've been obsessed with the practical logic of farmyards - the turning radius of tractors, where the chickens and ducks might go. It's not a place where stand-alone aesthetic decisions make a lot of sense.
