Home deconstruction: Can an entire house be recycled?
Deconstruction of a home to reuse or resell its materials is gaining popularity as a more environment-friendly alternative to demolition. Sometimes it even saves money.

This labor-intensive, job-creating approach takes unwanted buildings apart systematically and turns the pieces into new home construction or tax-deductible donations to nonprofit reuse centers, thus saving them from the landfill.
Construction and demolition debris take up more than one-third of landfill space annually, but on average, more than 60 percent of a house – and in some cases, more than 75 percent – could be reused or recycled, says Bradley Guy, who researches architecture and deconstruction at The Catholic University of America.
Of course, building materials have been reused for as long as there have been buildings. But where salvaging typically involves cherry-picking the pieces of most obvious value – stained-glass windows, ironwork – deconstruction reclaims as much of the building as possible.
Jack Williams and his wife, Jane York, spent 28 years in a 1950s ranch house in Leawood, Kan. When they decided to remodel and add an addition, they learned that their house's unstable foundation meant they would have to remove the house and start over on the site.
Mr. Williams had watched the demolition of a neighborhood house and regretted seeing still-useful material going to the dump.
"I'm driven by conservation because I hate to see stuff wasted," says Williams, a retired electrical engineer.
Working with the local Habitat for Humanity office, they found a certified deconstruction appraiser in Denver who traveled to Kansas to evaluate their home's materials. A local builder undertook the three-month deconstruction.
Williams and Ms. York ultimately donated or reused 82 percent of their home's materials, Williams estimates – everything except the insulation and drywall.
Appliances and other materials were hauled off to Habitat ReStore, a nonprofit reuse store affiliated with Habitat for Humanity. Scrap lumber was chipped into mulch. The foundation, driveway, and chimney were crushed onsite, becoming backfill around the new foundation.
