The CBS Studio Building is a seven-story office building at 49 East 52nd Street in Midtown Manhattan, New York City. Its had various uses at different times, including serving as a Vanderbilt family guest house, the first graduate school of the Juilliard School, CBS Radio studios and Columbia Records studio.
It is currently owned by the Fisher Brothers who converted it to an office building in conjunction with construction of the 45-story Park Avenue Plaza to its east.
It was built in 1908 as a guest house for the Vanderbilts who had a home a block away at Fifth Avenue (Manhattan) and 52nd. It was designed by Warren & Wetmore.
In 1924 the Vanderbilts sold it to the Juilliard Musical Foundation where it became Juilliard's first graduate school.
In 1939, CBS which had its corporate headquarters across the street at 485 Madison Avenue bought the building at 49 East 52nd Street to move its radio operations, except for the main network newsroom.
Architects Fellheimer & Wagner extensively renovated the building including eliminating the earlier Vanderbilt ornate external features eliminating windows for soundproofing and carved up the building into seven studios including one which could accommodate audiences of 300 as well as symphony orchestras that could broadcast. Arthur Godfrey broadcast from Studio 21 in the building and had his main office there. From 1974 until 1982, "CBS Radio Mystery Theatre" originated in Studio 27, renamed Studio G in honor of Arthur Godfrey.
