D-Build has information about how to "deconstruct," rather than demolish, a building; an online marketplace where people can buy and sell salvaged material; and a complementary store for trading the beds and side tables craftsmen have made from it. The site is still small—there are only a handful of products available and they tend to be pricey—but the idea has powerful potential. Buying a table made from part of an old house not only saves resources and landfill space, but also gives you a connection to the history of our built environment.
