When Cram and Ferguson's proposal for a small apartment tower behind a screen of shops on Walnut Street fell through, this house was designed for Samuel Wetherill with the intention that it would ultimately house the Art Alliance. Its exterior is the closest approximation to a Renaissance palazzo in the city. It is open to the public for its regularly scheduled art exhibits and also for its restaurant, most recently Opus 251. Rich wood paneling, especially the grand stair on the south side, suggests the original tonality before the interior was painted white to serve as a foil for the modern art that increasingly comprised its exhibitions. It was here that LeCorbusier during the course of his first American lecture tour famously refused to shake Paul P. Cret's hand.
