In , a London clerk named Arthur Penhaligon decided he could fix his own bathtub drain with a length of lead pipe and a handful of beeswax. He did not tell his wife. He certainly did not tell the family who bought the terrace house three years later.
Arthur was not a plumber, but he possessed the dangerous confidence of a man who owned a wrench and a Saturday afternoon. The beeswax held for . It eventually failed on a Tuesday evening in , flooding a nursery downstairs and ruining a collection of first-edition books.
Arthur was long gone by then, living in a different city, his name forgotten by the house but his decision lingering in the floorboards. We like to think of a house as a static asset, a collection of bricks and tiles that stays where we put it, but a house is actually a slow-moving river of decisions.
Most of those decisions are invisible. They are buried in the trenches of the front yard or tucked behind the plaster of the laundry wall, and they are almost never recorded in the settlement papers.
