CHICAGO — Bridge Investment Group’s office division has purchased One North LaSalle, a 47-story office tower in downtown Chicago. A joint venture of Hilco Real Estate and a pair of MB Real Estate executives sold the property for $113 million, according to Crain’s Chicago Business. The 493,738-square-foot building is currently 84.6 percent occupied. Originally built in 1929, the building has undergone more than $35 million in capital improvements over the last decade. An amenity floor known as The Landmark features a fitness center, conference facilities, lounge areas and a rooftop deck. Melissa Rubenstein, Annie Nicolau and Jay Miller of JLL will oversee lease-up of the property on behalf of Bridge.
