90-story mixed-use building could become Denver’s first supertall tower

Denver’s skyline may be about to undergo its biggest addition ever if the City approves a proposed $400 million project that would become the Mile High City’s first supertall skyscraper.

Six Fifty 17, designed by Carlos Ott, Crown Architecture, and Davis Partnership Architects, will provide over 1 million sf of space. The mixed-use building will include 248 luxury condominiums, a boutique hotel, 22,000 sf of retail space, and over 500 parking spaces.

A large collection of amenities will fill the massive space and includes multiple terraces (private and public) and pools, a spa with a sauna and steam rooms, a fitness center, a half-court basketball court, a bowling alley, and a game lounge with a pool table, foosball, and shuffleboard. Children will also be catered too with a playroom equipped with a custom climbing wall. Additional planned offerings include bicycle storage, pet grooming, day care, art consultation, and butler services.

Current plans peg Six Fifty 17 to reach the lofty heights of 1,000 feet, a number that would place the building as the 19^th tallest in the United States, nestled between JPMorgan Chase Tower in Houston and Two Prudential Plaza in Chicago. It would be 286 feet taller than Republic Plaza, Denver’s current tallest tower.

Greenwich Realty Capital hopes to break ground on the project in the summer of 2018.
