It’s not the best economic climate for building office space. But Don Chiofaro, a Boston-based developer seems unfazed. He is moving fast and furious to get approvals for a 1.5 million sq ft mixed -use project for Boston’s waterfront, betting the market will change by the time the project goes into construction.

In January he proposed a two-tower scheme for the site, a prime location between the New England Aquarium and the City’s new Greenway. But when that scheme was met with little enthusiasm, Chiofaro unveiled yet another design last week, a three-tower scheme designed by New York architect Kohn Pederson Fox. While this scheme is reportedly the developer's favorite, he has an arsenal of ten different designs that he is prepared to launch on the public until one sticks.
