The Mile-High City might be getting its very first supertall, courtesy of a developer from another American city that knows a thing or two about skyscrapers. Manhattan-based Greenwich Realty Capital wants to build Denver's tallest building at the site of a surface parking lot, which would be ripped up to give room for a 90-storey skyscraper reaching a height of 1,000 feet.

The developer gave the public a closer look at the project's finer details last week, revealing that Six Fifty 17 would boast over one million square feet of space, and host 284 luxury condominiums, a hotel, and 22,000 square feet of retail space. It would dwarf the state's current tallest building, the 218-metre Republic Plaza, which has been Colorado's skyscraper king since 1984.

Greenwich is hoping to break ground on the $400 million project in the summer of 2018, but it needs to navigate the city's approvals process first. Uruguayan architect Carlos Ott and local firm Davis Partnership Architects are collaborating on the project, which would include multiple terraces and pools, a fitness centre, and a number of sporting amenities like half-court basketball, a bowling alley, and a games lounge.
