Since it was established in 1990, Summerlin -- developed by The Howard Hughes Corp., which is an affiliate of General Growth Properties Inc. -- keeps expanding. The latest neighborhoods are to the west of the Las Vegas Beltway.

The 22,500-acre master-planned community still has about 7,000 acres yet to develop. One of the newest additions is mid-rise housing, in the form of C2 Lofts Summerlin Las Vegas, off West Charleston Boulevard and the Beltway.
