The part of the building that a historic preservation major would fight another person to save. Do not doubt them, their addiction to box cornice dentil work and clapboard is strong enough to make your meth-head neighbor cower in fear.
"My god. Would you look at that STUNNINGLY. FABULOUS. Decorative dentil work along THAt cornice line!!! Now THAT is a character defining feature." :')
