The ground level was built in 1921 and the limestone-clad first floor was added in 1930.","why_significant":"The nomination argues the building is significant in Commerce for its association with an important plumbing supply manufacturer and distributor, and in Architecture as a locally significant Art Deco commercial building and a representative work of architect Clarence Wunder. It also notes the company's long role in the Philadelphia plumbing trade, from its brass fittings origins to its later distribution business.","narrative":"Built in two phases at the northeast corner of 31st and Walnut Streets in West Philadelphia, the building combines a 1921 red brick warehouse with a 1930 limestone-clad Art Deco upper floor designed by Clarence Wunder. The first phase was a one-story pipe storage shed of about 19,000 square feet, permitted for the Bridgman Company at an estimated cost of $50,000. The 1930 addition, estimated at $35,000, gave the Hajoca Corporation a showroom and headquarters on Walnut Street, a commercial corridor with high visibility and access to major roads and rail lines. The main facade carries geometric and floral limestone carvings, a granite-based entrance and bronze cresting over the storefront windows. Hajoca traced its roots to 1858 and was among the largest plumbing supply firms in the country. The company moved its headquarters to Ardmore in 1957, and the building is noted for its intact exterior and its place in the company's history.","period_of_significance":"1921-1953","architect_builder":"Clarence E.
