Thor Equities plans 20-story office building at Fulton Market gateway

Thor Equities wants to build a 20-story office complex with ground-floor retail at the gateway to Fulton Market, adding to a flood of office inventory in the neighborhood.

The 400,000-square-foot building would cover an entire block bounded by Fulton, Green, Wayman and Halsted streets, according to Crain’s.

Thor took ownership of the last piece of the parcel when it paid $8.1 million for 306 North Halsted Street several weeks ago. It acquired most of the buildings in 2016 for $36 million, and another group of them this year when it paid $12.3 million for the former Isaacson & Stein Fish properties at 800-810 West Fulton Street.

Chicago developer Sterling Bay is planning a 19-story building next door to the Thor site at 333 North Green Street, one of three structures it’s adding to the block of Green. Those will add a total of 1.7 million square feet of office to a neighborhood with 6 million square feet of office in the pipeline.

Thor, which also owns the Palmer House Hilton in the Loop, has shed several other Loop properties in recent months as it has turned its attention to Fulton Market, where it also owns buildings in the 900 block of Fulton, the 200 block of North Peoria Street and the 1200 block of Randolph Street.
