From Stewart Brand’s really rather good How Buildings Learn, What happens after they’re built. (if you’re interested you should try to get the US edition as the (well deserved) criticism of Richard Rogers was for some reason removed from the UK edition).

Pump Square of Siasconsett Nantucket, founded by whalers in the 1680s. The full taxonomy of add-ons is displayed. A former shanty in the foreground has become an ice cream saloon.

Henry Chandlee Forman’s chart of how whale houses grew (viewed as somewhat fanciful by other building historians). The original “great room” of these houses was only 11 by 13 feet.

There’s a wonderful summary of the whole book here.
