I wish I had something to say about these apartments. They date from around 1963, they're at 6634 W. 9th Street in Oak Lawn, they're called the the Pavilion Park Condominiums, and that's all I know.
Well, that, and they apparently had a crazy genius mason.
Apart from this one architectural outburst, there's nothing at all remarkable about these buildings. They're utterly plain Midcentury stuff. They don't continue any evident trends on the street or the surrounding neighborhood. They pop up, do their thing, and go away again.
I sure would love to know if this designer did any other work around town!
