A vintage 17-story office tower at 70 E. Lake Street in Chicago’s East Loop has a new owner and a new life on the way as apartments. The deal is part of the broader wave of downtown adaptive reuse, as investors keep scooping up older office buildings and reworking them into housing. The property sits a half block west of Michigan Avenue, with retail space along Lake Street and easy access to CTA transit.
According to Crain's Chicago Business, the buyer plans to convert the building into residential units. Marketing materials from Cushman & Wakefield peg the 1927 structure at roughly 141,593 square feet and show it was about 63 percent leased before the sale. Those same materials highlight the narrow, well-windowed floor plates and ground-floor retail, features brokers say help make an apartment conversion pencil out.
Building history and how the deal came together
The tower hit the market earlier this year as a clear conversion candidate, with brokers pitching a purchase basis in the roughly $10 million to $12 million range. The property had been held by a family office represented by Ansonia Properties since 1993, according to The Real Deal, and most of the existing leases included landlord termination rights that would streamline a shift to apartments. That setup helped draw the eye of buyers focused on adaptive reuse plays.
What to expect next
The sale of 70 E. Lake slots into a string of downtown deals and listings that coverage has tied to ongoing office weakness and growing interest in residential conversions, per Crain's Chicago Business. Early reporting has not identified the buyer, disclosed the sale price, or pinned down a construction timeline, and those details are expected to surface as plans move through city permitting. For nearby workers and residents, the project will mean a period of construction on a busy stretch of the Loop and, eventually, a fresh batch of apartments steps from the Magnificent Mile.
