The Fallon Company, a leading national real estate development firm with offices in Boston, Charlotte, and Nashville, marked a major milestone today with the topping off of One Harbor Shore, the final building in the company’s transformative 21-acre Fan Pier master plan. The event included remarks from company leadership, a ceremonial beam signing and hoisting with Iron Workers Union Local No. 7, and a luncheon recognizing the construction team’s efforts. Executive leadership, project partners, and contractors gathered on site to mark the completion of this 122-unit luxury condominium building, a defining symbol of the Seaport’s evolution.
