Upon realizing that the resort needed more rooms, Prell hired Del Webb in 1954 to build additional units.
The project took five months to construct, and was completed by 1955.
Originally known as the Sahara Oasis Motel, the addition contained 192 rooms.
It consisted of seven interconnected buildings, one of which connected to the main resort through an air-conditioned walkway.
The addition was designed by Martin Stern Jr. as a two-story motel wing, built out in an "E"-like shape just south of the quadrangle structures.
The addition marked Stern's first project in Las Vegas.

In 1959, a $3.5 million construction and remodeling project began at Hotel Sahara, including the start of construction on a 14-story hotel tower.
The tower was designed by Stern, and construction was handled by Del E. Webb Construction Company.
It was built southeast of the hotel pool.
Construction on the tower had reached the eighth floor in November 1959, and the project was topped out in early 1960.
Aside from the tower, other new features included a coffee shop with seating for 300 people, and a 700-person convention hall, located on the resort's north side.
The 14-story Sahara Tower (later the Tunis Tower) opened in June 1960, adding 204 additional rooms for a total of 604.
It was the tallest building in Nevada at the time.
A flashing, electric clock was located atop the tower.
The clock included the time as well as the temperature, and was topped by a letter "S" sign.
Also added was a 127-foot vertical roadside sign, designed by YESCO and installed in front of the resort.

By July 1961, there were plans for a $2.5 million renovation of the Hotel Sahara.
Also planned was a 24-story hotel tower, designed by Stern, that would cost $4.5 million.
The project would also include a parking garage along the Las Vegas Strip.
Del E. Webb Corporation completed a purchase of the Sahara later in 1961, by acquiring shares in its corporate owner, the Sahara-Nevada Corporation.
At the time, state law for gaming licenses meant that every shareholder in a company would have to undergo the mandated investigations of the Nevada Gaming Control Board.
Because large corporations have many shareholders, this essentially prevented such companies from operating casinos in Nevada.
Del Webb devised a plan to work around this issue by operating as a landlord, meaning its shareholders would not need to undergo investigations.
A separate organization, Consolidated Casino Corporation, was set up by Del Webb to operate the casino.
Jacobson, Prell and Winter owned Consolidated Casino Corporation, and Prell and Winter were also retained to serve, respectively, as chairman of the board and president of Sahara-Nevada Corporation.
An expansion of the restaurant and lounge facilities was underway in late 1961, and an enlargement of the Casbar Theater was completed in early 1962.

A groundbreaking ceremony was held on February 9, 1962, for the $6 million, 24-story Sahara Skyscraper hotel tower, located next to the Sahara Tower.
The new tower, built by Del Webb, was expected to measure 260 feet in height.
It would add 400 rooms, for a total of 1,000.
Three swimming pools, including the original Olympic pool, opened in April 1962, after construction and remodeling.
A keno facility opened later that year, making the Sahara the second hotel on the Strip to offer the game.
The House of Lords steakhouse opened in August 1962.
It became a popular hangout among celebrities who performed at the Sahara, including the Rat Pack.
The restaurant was modeled after the real House of Lords in the United Kingdom.

By October 1962, construction on the new tower had reached its 17th floor.
A Don the Beachcomber restaurant opened the following month.
At the time, Prell and other Sahara executives sought to rename the adjacent San Francisco Avenue as Sahara Avenue.
Beldon Katleman, owner of the former El Rancho Vegas across the street, objected to the proposal, stating that the road should be renamed after his hotel-casino property.
Despite the opposition, the street was renamed after the Sahara.
