There were two areas where right of ancient lights would cause height restrictions. While the rights on the southern side ceased to be a problem after the owners of those rights gave concessions, the rights on the eastern side were dealt with by sloping the roof away from the street from the fourth floor up, which affected not only the floorplan of the structure but meant that the interior recording tower could not be continued up to the top floor. (Thus, one studio on the top floor was actually outside the central studio core structure.)
