The towers to your above right represent the biggest of the would-be spires rising on the site of the Government Center Garage in downtown Boston. The cylindrical one would stretch to 528 feet and, at 1 million square feet with the capacity to hold up to 5,000 workers, "would be the largest office building under construction in the city," according to the Globe's Tim Logan. It's designed by Pelli Clarke Pelli and CBT Architects.
The residential portion of the Government Center Garage redo, designed by CBT, is supposed to be 480 feet, or 45 stories, and contain 486 apartments as well as ground-floor retail. Both towers would be developed by HYM Investment, which got the city's O.K. two years ago for what could be a six-building project with 812 residences and a hotel, but that needs individual design approvals for each tower. Both of these rendered towers are, of course,quite tall by Boston standards. Settle in.
