Now, the surviving structures are threatened again, this time by the neighborhood's revival. A new restaurant called Martha just opened in the Weisbrod & Hess metal shop. With building lots for housing in demand, the owners of the boiler house and loading facility put the buildings and an adjacent parking lot on the market. Hoping to see the old structures incorporated into the new development, residents have posted a petition on Change.org calling for their preservation. This could be the last chance to save a piece of Philadelphia's great beer history.
