Berkshire Bank became Massachusetts’ largest state-chartered bank earlier this year with its acquisition of Commerce Bancshares Corp. It has since revealed it is moving its headquarters from Western Massachusetts to Boston.

Transwestern Consulting Group announced Thursday it represented the banking company in a 10,600 SF lease at 60 State St. downtown. Berkshire Hills Bancorp, Berkshire Bank’s parent company, will have its office on the tower’s 38th floor.

"This new headquarters location reflects our leading role as a New England regional bank and northeastern financial institution with national specialty lending teams,” Berkshire Bank CEO Michael Daly said in a prepared statement. “With our central presence in New England's financial hub, we're expanding our Boston area banking operations and enhancing the resources we provide to all of our regional banking markets."

The formerly Pittsfield-based company is expected to move into its new headquarters in December. The office will house senior executives, wealth managers and local commercial, retail and private bankers.
