Chinatown developer Xiang Yong Wei redid the place late 2009- early 2010. Its supposed to be some kind of community outreach place besides an apartment. Storefront was supposed to become a culinary school and food court, second floor computer labs, third floor art studios/gallery.

The name of the place appears as PA Ridge, Penn Future Resource Center, and Ridge Tower on three different sources, so I can’t tell which is the current name.

Besides Prouty, the place was the Lippencott woodworking factory, Souders & Co. Box Factory,  Dworkin Light Fixtures, Precision Thermometer and Instrument Co, Giese and Goodyear Co, Merritt and Co locker manufacturer, Clarion Record Manufacturing Company, Velvetone Manufacturing co, Gordon cash Register Co, Charles F. May Co, Philadelphia Safety Co, and A-Durable Textile Inc. Obviously, some of these companies were using the building at the same time.

The box factory had a big fire in 1919 or 20 and the building was heavily altered after that.

You’re kind of our hero.

I had a friend who lived there about 10 years ago.  He shared a huge space on one of the upper floors with a few other people.  The space was about 2000 sq. ft and was entirely open, but had half-walls and screens set up to separate the bedrooms.  Otherwise it just looked like a big warehouse.  And there were old arcade games and pinball machines everywhere, just randomly placed throughout the apartment — I think they were there before he moved in.  He had an amazing view of the viaduct and the skyline.
