Inside the Pittsburgh Athletic Association, Mister Rogers swam laps to stay fit. From the water, he could see its elegant terracotta balcony, its double barrel-vaulted ceiling and the Guastavino arches that supported it.

Removing the pool took a year, but the balcony, ceiling, arches and so much more of this Oakland landmark’s architectural grandeur remains as Strada Architecture and owner Walnut Capital continue its restoration.

The PAA was designed by architect Benno Janssen, who trained in Paris. The 110-year-old building’s exterior features athletes, decorative medallions and wrestlers. Its lobby, dining, meeting and reception rooms are being restored; the remaining space will become offices.

“The four largest rooms on the first floor will have 17-foot-high ceilings,” said Sam Kriegler, an architect overseeing the historic restoration for Strada Architecture.
