By February 1962, the tower was planned to include 31 floors, making it the tallest building in Nevada. While plans for a separate hotel structure were being made, work began on the tower by pouring concrete on a continuous 24-hour schedule. The concrete pour was done with a slip forming method. With 21 floors expected to be added to the tower over a 12-day period, it was expected to reach the 24th floor by the end of the month. In March 1962, at the request of Caroll, Clark County Commissioners removed a restriction which specified that gaming licenses could only be issued for ground-level casinos, as Caroll wanted to open a casino on the second floor of the Landmark's shopping center. That month, Caroll received a $450,000 loan from Appliance Buyers Credit Corporation (ABCC), a subsidiary of RCA-Whirlpool.
