Many of the buildings are following the pattern of Miami, where residential towers offer luxury-hotel amenities such as concierge service, valet parking, restaurants, fitness centers, and spas. Much of the demand is coming from people who want to live in convenient urban settings, near bookstores, jazz clubs, theaters, and good restaurants.

A 972-square-foot one-bedroom unit at Icon Las Vegas, the future Reggie Jackson hangout that Related Cos. is building, starts north of $600,000.

But for those with money, the towers, with their luxury amenities and chic granite-and-wood fixtures, hold an allure even at prices that range from $500 to $1,000 a square foot.

??With the poker boom, I find myself spending at least three months a year in Vegas, and we needed a home there,? said Barry Greenstein, a resident of Rancho Palos Verdes, south of Los Angeles, and a professional poker player.

Greenstein paid $1.2 million for a 2,300-square-foot unit on the 16th floor of the first Panorama tower because of its proximity to the Bellagio, where he won $215,969 in a World Poker Tour no-limit Texas hold ?em event last year.

??Some of the other high-stakes players are moving into that building, so we will have a little community there,? he said.
