Finding new uses for old buildings, especially when they’re architecturally interesting or well located, creates substantial value for the environment, the local context, and often the bottom line. Over the years, we have converted former office buildings into retail centers, museums, and hotels and, on the flip side, former hotels into offices. We’ve converted dairy barns and warehouses into residences and residences into offices and schools. Old postal facilities and police stations have been transformed into elementary schools. A YWCA becomes a museum and its basketball court, an auditorium. In most cases, the new use reinvigorated both a worn-out building and even the whole neighborhood.
