New look and expansion proposed for One Post Office Square tower Developers Anchor Line Partners and JLL propose to reposition and expand the aging 41-story One Post Office Square office tower overlooking Norman Leventhal Park in Boston’s Financial District, giving the tower a striking new glass facade and constructing additions totaling 140,000 square feet of new space. The $250 million project, designed by Gensler, would start construction in the third quarter of 2018, following anchor tenant Putnam Investments’ move from 300,000 square at One Post Office Square to 250,000 square feet at nearby 100 Federal Street. The proposed project would expand the 832,000-square-foot One Post Office Square to just shy of one million square feet in size, constructing corner infill areas along the existing tower and a new 10-story building atop the building’s existing six-story parking garage along Oliver Street; a total of 140,000 square feet of new space would be constructed. The existing building’s facade would be fully re-cladded with floor-to-ceiling glass panels, and new outdoor spaces would be constructed throughout the building.
