They were built as speculative houses and were designed by A.W. Dilks.","why_significant":"The nomination argues the houses are among Philadelphia's most important examples of the Queen Anne style, showing its essential features in a unified streetscape. It also presents them as representing the lifestyle of the industrial and railroad elite who settled Powelton and as examples of the work of architect A.W. Dilks in his early career.","narrative":"Three pairs of Queen Anne double houses line the south side of the 3300 block of Arch Street in Philadelphia's Powelton neighborhood. Built in 1890 as speculative rental houses, they were designed by architect A.W. Dilks for developers Frederick Poth, a brewer, and Edward Schmidt, of Schmidt's brewery. Each house has a three-story projecting bay capped by a wall gable, wood porches with knee braces and turned posts, and a double-angled mansard roof clad in fish-scale red terra cotta shingles. The pairs differ in their front compositions while sharing the same rear design. Interiors have patterned tile vestibules, a walnut stair, and plaster cornices with deep grooves, with most decoration concentrated near the entrance. The nomination treats the group as a fine example of the style and as a record of the lifestyle of the railroad and industrial elite who settled the area after the Powel estate was divided in the 1880s.","period_of_significance":"1890","architect_builder":"A.W.
