Reuse existing structures
If possible, find a use for existing structures on the site
Condition is key, but it makes more sense to repair an old outbuilding than it does to tear it down and start from scratch. Not all existing structures can be adapted to new uses or the needs of homeowners, but it's an option worth exploring. Evaluating existing structures for stability and hazardous materials, such as lead, asbestosMineral fiber once commonly used in many building materials, including insulation, fireproof siding, and resilient flooring. Inhalation of invisible asbestos fibers can lead to chest and abdominal cancers as well as scarring of the lungs. The use of asbestos in some products has been banned by the EPA and the U.S. Consumer Products Safety Commission; manufacturers also have adopted voluntary limitations on its use. When found in older buildings (most commonly in floor tiles, pipe and furnace insulation, or asbestos shingles), the product's friability is a major determinant in how it must be handled during renovations.
