The Westinghouse Building (now known by its street address, Eleven Stanwix) was designed by Harrison & Abramovitz, who completely changed Pittsburgh’s skyline in the years between the Second World War and the Postmodernist era of the 1980s.
Years ago old Pa Pitt said that the building reminded him of two Mies van der Rohe buildings stacked one on top of another. The building has a Miesian colonnaded porch, but there is an essential difference, and the difference is in favor of Mies.
In a Mies building, the porch creates a useful space that is a transition between outside and inside. You can set up tables on the porch if you like, and they will be out of the weather. People caught in a storm can run to the porch and be sheltered until security chases them back out into the rain. But here the porch is shallow and nearly useless. It does not provide shelter, and the space between the columns and the building is so tight that it eliminates the possibility of using the porch for much. The tables above are pleasant on a clear day, but they are exposed to the weather, and you would not want to sit there in the rain.
In fact, as insulting as it is to say this to a pair of distinguished modernists like Harrison & Abramovitz, this porch is merely decorative.
We also have pictures of the Westinghouse building from Mount Washington, and from the Monongahela River.
