The diamond grid is not an ornamental facing: it holds up the building, along with a central core. “Diagrid construction” is a little more common today, but still fairly unusual; perhaps the most famous or notorious example of it is the Gherkin in London. This was a very early example. It was finished in 1964, and although it was originally built for IBM, it fits its current owner very well: its steel grid is a good demonstration of what steelworkers are capable of. The architects were the New Orleans firm of Curtis and Davis.
This is not Father Pitt’s favorite building downtown, but it was one of the last works of a distinguished modern architect: William Lescaze, who died in 1969, the year after One Oliver Plaza was built. The building has had several names since then; it now goes by the name K&L Gates Center. Old Pa Pitt’s friend Dr. Boli has remarked that the names at the tops of the skyscrapers are a good index of who is most ruthlessly exploiting the masses at the moment. K&L Gates is a gigantic law firm.
Old Pa Pitt’s fascination with small apartment buildings is hard to explain, except that—as he has mentioned before—they often gave lesser architects a chance to execute unusual ideas. This building is made of very simple elements, but arranged in an unusual rhythm, the balconies forming strong verticals that are accented by brick projections at the roofline.
The architectural parts of the Sixteenth Street or David McCullough Bridge, built in 1923, were designed by Warren and Wetmore, architects of Grand Central Station in New York. The fact that the bridge does not fall down is attributable to the engineer, H. G. Balcom.
Throughout the year 2022, old Pa Pitt managed to put up at least one new article every day. To celebrate the changing of the years, here are twelve of his favorite pictures from last year, one for each month:
A vase of witch hazel.
Church of the Ascension, Shadyside.
Crocuses in the rain.
Fox squirrel.
Interior of Heinz Chapel.
Mammatus clouds at sunset.
Spotted Lanternfly nymph.
Retreating storm clouds behind the spire of Third Presbyterian Church, Shadyside.
Atlas on the Kaufmann’s Clock.
Chimney pots on the South Side.
The skyline of downtown with November leaves.
