It is owned and operated by Wynn Resorts, and was built on the former site of the Desert Inn resort, which opened in 1950. Casino developer Steve Wynn purchased and closed the Desert Inn during 2000, with plans to build a new resort on the site. The design phase lasted two and a half years, and construction began on October 31, 2002, with Marnell Corrao Associates as general contractor. At a cost of $2.7 billion, Wynn Las Vegas was the most expensive resort ever built, beating Wynn's $1.6 billion Bellagio, which opened on the Strip in 1998.
