<P> The Cosmopolitan's design team was led by Friedmutter Group as executive architect, with Arquitectonica as the design architect for the building's themed exterior . The building was engineered by DeSimone Consulting Engineers . The interior design team included Digital Kitchen, Prophet, the Friedmutter Group, The Rockwell Group, Jeffrey Beers, Adam Tihany, and Bentel & Bentel . </P> <P> The resort was built on what used to be the parking lot for the Jockey Club . Because the Cosmopolitan occupies much of the parking lot, it was agreed that the Club residents could use part of the Cosmopolitan's parking garage . </P> <P> The Cosmopolitan was the second Las Vegas hotel, after The Palazzo, to feature an underground parking garage underneath the hotel . As a result, the parking garage was built first . In December 2007, work finished on the 70 - foot (21 m) hole for the parking structure, while other foundation work remained in progress . The hotel was originally planned to open and be operated by Hyatt as the Grand Hyatt Las Vegas . </P> <P> Original plans called for the casino to be on the second floor, but this was later changed and the casino was built on ground level, like most other Las Vegas hotel - casinos . Planned condo units were cancelled and replaced with studios and other hotel rooms . </P>
