Love the buildings in Amsterdam – leaning every which way but straight. Many were intentionally built to lean slightly forward so that the hook on an outcrop at the top could be used to haul furniture and other property up and in without bashing the front of the house. If they’re leaning sideways, though, you’ve got a problem. Here are a couple of my sketches of the architecture of Amsterdam. I will say that the leaning left right and forward does take the pressure off having to draw things square!
