Wharfing Out, Porching Out

July 9th, 2011
expansion, construction  [html]

One of the ways that costal cities expand is 'wharfing out'. Wharves are built to provide more dock area, and then later people come along and fill in the area between the wharves to get more land area. Similarly, one of the ways houses expand is to build a porch, and then later make it part of the house. Both of these are expansion in stages, increasing the interface with the outside and then descreasing it. A straight up expansion is also possible, but going through the intermediate step of wharves or porches makes the next step easier to picture.

(Read about city expansion in gaining ground: a history of landmaking in boston and house expansion in how buildings learn, what happens after they're built. I really liked both of these books.)

What do executives do, anyway?
