@ntxdave Memory. This one is basically like your typical tract ranch with gable ends and a center bump-out. That combined with all the details and elevations I've done over the years. I start with an idea in my mind and go from there. Sometimes I'll mull things over in my head while before I go to sleep. I guess you can look at a lot of house pictures. I stick with standard wall heights, roof slopes, windows, roof types, etc.
