Once completed, the Seventh Floor - breathtaking in its elegance and refinement - consisted of a 1,200-seat Concert Hall, the famed Round Room Dining Room and the Grand Foyer, which together include more than 45,000 square feet of entertaining space in downtown Toronto.  Boasting a full-service kitchen and additional dining areas known as The Clipper Rooms, the Seventh Floor hosted Toronto's finest, for high society events including luncheons and tea dances to opera, theatre, classical music performances, gala dinners and Debutante balls.

At last, the vision had been realized, through Lady Eaton's collaboration with Carlu. 

Opened March 26, 1931 with a Gala concert, the Seventh Floor Concert Hall was soon considered one of the finest auditoriums in North America, often referred to as the sister to New York's Carnegie Hall.  Known for its superb acoustics, the Hall played host to major performers of the day, including Billie Holiday, Duke Ellington, Mario Lanza, Frank Sinatra and Canada's own Glenn Gould, for the next three decades.
