I don't think this will win any design awards, but it is a nice looking building. And you're right, it is time Philly had some skinny skyscrapers. There are a number of buildings in the city that are twice as wide and half as tall as I think they should be, like the Kennedy House:
Such a waste of real estate, but most of them were built before 1Lib broke the City Hall height limit.
Also, retaining the houses at the base annoys me. I don't know whether they are historically significant or anything, but I think it separates the base from the tower. They are at two different scales, and they do not really talk to one another. It reminds me of the Hearst Tower in NYC, where they have the original historical building retained at the base then the Foster-designed tower built on top of it. A weird marriage.
