The long‑talked‑about conversion of 208 S. LaSalle from office space to housing is finally moving from PowerPoint to power tools. The city has signed off on an interior demolition permit for The LaSalle Residences, clearing the way for crews to start tearing out four mid‑level floors that are slated to become roughly 168 apartments, including a sizable affordable set‑aside. For now, crews will focus on gutting the interiors before a separate renovation permit is filed, and the developer is still keeping any firm construction timetable under wraps.
Interior demo permit issued
According to Urbanize Chicago, the new interior demolition permit allows general contractor Break Thru Enterprises to clear out floors 13 through 16 for the planned apartment conversion. The work covers about 222,500 square feet and is part of an estimated $100 million overhaul. A separate renovation permit will be needed before individual units can be built. Plans call for upgrades that include swapping out single‑pane windows for high‑performance insulated glass and installing modern mechanical systems throughout the converted space.
Historic shell, modern interiors
The 1914 Continental and Commercial National Bank building, designed by D.H. Burnham & Co., was designated a Chicago Landmark and added to the National Register of Historic Places in 2007, according to Preservation Chicago. Prime Group has already brought much of the old office tower back to life. The lower levels now house a JW Marriott, and upper floors operate as The LaSalle Hotel. Recent renderings show interior design work by Lamar Johnson Collaborative and Lucien Lagrange Studio. Earlier coverage and imagery from Chicago YIMBY highlighted a larger initial proposal and detailed the project’s tax‑increment financing request.
Part of the LaSalle Street reimagining push
The 208 S. LaSalle conversion is one of the higher‑profile pieces of the city’s LaSalle Street Reimagined initiative, which aims to pump residential life back into the Financial District. Mayor Brandon Johnson has publicly backed the program, as reported by WTTW. The initiative ties public support to affordability requirements and other conditions that are supposed to ensure new residents help prop up downtown retail and transit use. Preservation advocates and housing organizers say projects like this will be an early test of whether LaSalle can be reactivated without sacrificing its landmark character.
Next steps
With the interior demo permit in hand, Break Thru Enterprises can now begin gutting the targeted floors while the development team finalizes drawings and applications for the renovation permit, Urbanize Chicago reports. The developer has yet to announce a construction schedule or leasing plan, and additional city approvals will still be needed before any apartments open. Even so, the permit marks one of the clearest signs yet that another underused LaSalle Street office stack is on its way to becoming new downtown homes.
