Not too many people might think to look for architectural salvage in the Blue Valley industrial district just off Truman Road. But hidden inside Warehouse One, which is best known for buying and reselling business equipment, is a trove of architectural items gleaned from strange and unusual places. The salvage ranges from the practical to the exotic: Brass sculptures by the Mexican artist Sergio Bustamante sit alongside purple glass blocks from the 1950s, which were used to let sunlight through to tunnels beneath the sidewalks in San Francisco. Suppliers regularly drop off ornamental ceiling tin, old doorknobs, and a steady supply of claw-foot bathtubs. Also, a selection of statues and tiles from the Country Club Plaza and wrought iron from downtown theaters are popular for people who want something unique to brag about in their homes. The 8-foot tall Chinese vase has yet to be sold.
