Sales have launched for the Waldorf Astoria Residences in downtown St. Petersburg, a project that will become the city’s tallest tower and its first hotel-branded luxury condominium.

The 50-story, 539-foot-tall tower planned for 150 2nd Avenue South will include 163 condominiums, 73,000 square feet of Class A office space, 10,000 square feet of ground-floor retail, and an extensive collection of high-end residential amenities.

Pricing for the luxury condominiums start at $2.5 million.

The $500 million tower, which will be managed by Hilton, is being co-developed by Miami-based Property Markets Group and St. Petersburg-based Feldman Equities, who own the adjacent City Center office building. Vancouver-based City Office REIT and Orlando-based Tower Realty Partners are also involved. Smith & Associates Real Estate is overseeing the sales.
