AvalonBay raised the final beam on the Avalon Exeter on September 11th. Joined by vice president of development, Michael Roberts and David Gillespie, construction workers signed the last I-beam placed at the top of the project. The $100 million Avalon Exeter marks the completion of AvalonBay's first luxury apartment development in the city at the Prudential Center. The 28-story sustainable development designed by Elkus Manfredi Architects will have 187 residential units, consisting of studio, one, two, and three bedroom apartment homes.
