It had three floors. The lower floor contained store rooms, a billiard room, café, kitchen and pantry. The 36-by-36-foot lodge hall, with seating for 400,
was on one side of the second floor, and the the other side had a large smoking room and the ladies’ reception room and parlor. The third floor consisted of apartments for lodge members.
A look inside. (supposedly)

Either this is an entirely different place, or the oval auditorium is on the backside of the building shown in
GW's photograph.
I see no exterior evidence of an oval room with windows. (I guess the windows could be fake...painted like tromp l'oeil)
The oval room would be visible in an aerial. (I believe the 3rd floor apartments were probably built around it)

One small correction GW:
The building was located at Palos Verdes & 7th Street (the photograph was taken in 1911, so maybe that's where you got 11th street)
The official address was 207 W. 7th Street.
