As a baby boomer who has spent over 35 years in the architectural and real estate development professions, I'm aware that the current economic downturn has made many of my peers revaluate where they are going in both their personal and professional lives. Some have regretfully waived the defeat flag and headed for retirement. Others have reinvented themselves in second careers, and in so doing given themselves exciting new lives.
In an analogous rebirth, perfectly good building material that once would have been buried in a landfill is now enjoying a second life through creative reuse.
Building-materials reuse was once considered the backwater of do-it-yourself homeowners on a limited budget. Today reuse serves a vital role within the mainstream of state-of-the-art design and construction, in both the residential and commercial sectors of the industry. This trend is driven by building professionals and building owners who have become more conscious of the financial and environmental benefits of materials reuse and the potential tax benefits of choosing deconstruction over demolition.
In California, an entirely new driver is the new CalGreen Building Code, adopted in 2011. Although building industry professionals have mixed opinions of the code, it is now the law. The code mandates requirements that encourage the adaptive reuse of materials and, in some municipalities, actually offer developers and owners incentives for creatively reusing building materials. Although the code only affects construction in California, a similar set of codes and mandates is in the works with the International Code Council, which will affect the majority of states when adopted over the next few years.
The reuse of building materials falls into three basic categories:
1. Conventional reuse of materials
2. Adaptive reuse of materials
3. Recycled content reuse of materials
The conventional reuse of building materials involves building or remodeling with materials salvaged from older structures. One of my favorite examples is the "Big Dig House." The Big Dig was one of the largest infrastructure projects in North America in the late 20th century and involved the creation of a major loop transportation system around the city of Boston. The Big Dig House was constructed with over 60,000 pounds of salvaged material from structures that were demolished or deconstructed in the path of the Big Dig. The final construction cost was approximately half that of a comparable custom home built with conventional new materials.

Adaptive reuse involves salvaging a material that was used for one purpose in its original structure and reusing it for a different purpose within a new or remodeled structure. For example, a glass curtain wall from a commercial building might be used to create a new residential sun room. A more spectacular example is the Malibu "Wing House" in which architect David Hertz used wings from a retired 747 jetliner as the roof of a new custom home.

Taking Hertz's vision to the extreme is a custom hotel suite in Costa Rica constructed from the entire fuselage of a recycled 727. If planes could talk, this one would tell you what a great second life it's having at the beach!
The third and final category of building material reuse is recycled building material content, which involves taking previously used material and, through some type of manufacturing process, turning it into new building material. This is an exciting niche within the building industry that has inspired both small entrepreneurs and Fortune 500 companies to come up with new products made from old products.
