A modest 1,300sf home north of Seattle has been lovingly disassembled with a new home rebuilt from the components. Due to rising landfill costs, tighter recycling guidelines and the growing trend toward ecologically sound building methods, this sort of home “deconstruction,” as the practice is called, is starting to catch on. About 1,000 homes a year are disassembled this way, according to the US Building Materials Reuse Association, a nonprofit educational group in State College, Pa., which reports growing interest in the practice.
