On Florida Avenue, a street that runs behind the Uptown business district in Mount Lebanon, two apartment buildings in a toned-down version of Moderne streamlining face each other. The most striking feature of number 666 is the stairwell set into a tall groove with a two-floor window of glass blocks.
The decorative brickwork at the corners suggests quoins, but in a modernistic manner.
Across the street is a pair of identical buildings with less streamlining and no abstract quoins.
Both buildings would probably have had windows with more character when they were new.
