Old Post Office

Chicago’s Old Post Office, located at 433 West Van Buren Street, is the singularly most unique site in the nation, comprised of a 12.3-acre site consisting of the iconic former Main Chicago Post Office centrally located in the heart of Chicago’s West Loop Central Business District. Situated along Chicago’s iconic Chicago River to the east, The Old Post Office is an integral part of a world-class urban fabric with direct access to world-class amenities. There is no other site in the nation with a more strategically positioned asset that is more centrally located in the heart of a world-class city approaching the size and scale of The Post Office site.

The historic art deco structure is 12 stories tall totaling 2,500,000 square feet of office-lead mixed-use development. The building boasts 280,000 square foot floor plates with efficient column spacing and soaring 19-foot ceiling heights, granting generous access to natural day light and providing users with a truly unique opportunity for enhanced collaboration and productivity across a single floor plate.

The building underwent an 800 million-dollar holistic transformation, completely renovating it from the inside out, restoring the building’s limestone façade and replacing 2,200 windows. The structure has been completely stripped of its old mechanical system and is further enhanced through brand new state-of-the-art utilities that have ushered in the next generation of business. These monumental updates facilitated in the building’s win for both Downtown Redevelopment of the Year, as well as Special Achievement of the Year in 2020 at the Greater Chicago Food Depository Awards. In the same year, the building also brought home the award for Deal of the Year for securing Uber as a major building tenant.
