During a Midtown Development Review Committee meeting last month, real estate group Granite Properties debuted toned-down designs for a colossal mixed-use project that’s slated to rise at the corner of 17th and Spring streets: Midtown Union.

A beefier, more angular office tower design had been traded for a more buttoned-up look with long glassy panels that shoot toward the sky.

Now, architecture firm Cooper Carry has unveiled imagery that depicts fresh vantage points on the updated drafts.

Once realized, the multi-tower Midtown Union would comprise some 1.3 million square feet of residences, retail, hotel rooms, and office space.

The Midtown DRC green-lit the upgraded designs during the September meeting, after “working with committee members to resolve several outstanding issues, such as parking deck screening, public art, and street level facade enhancements,” reads a Midtown Alliance blog post.

Cooper Carry’s latest renderings also spotlight one of the project’s main office tenants, investment management company Invesco, which is expected to take up roughly half of the 600,000 square feet of office space planned.

The development’s hotel flag has not yet been announced, but Street Lights Residential has been enlisted to handle the apartment component.

Midtown Union’s first phase promises a 250-key hotel, 350 residences, 100,000 square feet of retail space, and roughly 1,800 parking spots.

Earlier this month, Midtown’s former Arthritis Foundation building was imploded on the site to clear the way for construction.

The complex is scheduled to begin opening in 2022.
