Wynn Las Vegas,a Forbes Five Star luxury hotel and casino, is a luxury resort and casino located on the Las Vegas Strip in Paradise, Nevada, United States.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 out Wynn's $1.6 billion Bellagio, which opened on the Strip in 1998.
Wynn Las Vegas opened on April 28, 2005, with 2,716 rooms and a 111,000 sq ft (10,300 m2) casino. At the time, its 45-story hotel tower was the tallest building in Nevada. A sister property, Encore Las Vegas, was opened by Wynn Resorts in December 2008. Located directly north of the resort, Encore added a second hotel tower and additional gaming space, as well as several restaurants and clubs. In total, the 215-acre (87 ha) Wynn complex contains 4,748 rooms and 188,786 sq ft (17,538.8 m2) of gaming space. Wynn declared his $5.2 billion complex finished in May 2010, following additions made at Encore.
