ARCHITECT took a break from the American Institute of Architects' 2016 National Convention, held in Philadelphia in May, to visit architectural salvage dealer Provenance Cos. We spoke with its co-owner Scott Lash about the company's deconstruction work, sourcing high-end architectural salvage, and its process of refinishing products and materials for new uses. Provenance's work spans the country, including the herringbone-style ipe floor in the Court at the new Barnes Foundation, in Philadelphia, designed by New York–based practice Tod Williams and Billie Tsien Architects.
