Project Description
Anchor Line Partners and Jones Lang LaSalle Corporation propose to upgrade the existing property at One Post Office Square, Boston. The existing property contains a 41-story, 515 foot tall multi-tenant office tower, and a 6-story garage with 8 levels of parking and 371 spaces. The upgrades to the office tower will include the replacement of the existing façade with a glass curtainwall from the ground level to level 30, an overclad system between levels 31 and 38, along with the addition of mid-level and roof level attractions, and the addition of infill areas below existing cantilevered corners. The existing parking structure and associated spaces will be demolished and replaced by a new 18 story structure with ground floor retail and drop-off for an automated parking garage. The automated parking garage will include 3 stories above grade and 2 stories below, with a 13-story addition above the garage that extends the existing office floor plates from the One Post Office Square office tower, and two floors of mechanical space above.
