A tower crane permit was issued November 22nd by the City of Chicago for 151 West Illinois Street in River North. Guess what? There’s no tower crane at 151 West Illinois Street in River North. Nor is there one in the 400 block of North LaSalle. But that might change very soon.

Workers from Pepper Construction have been at this intersection the past couple days, getting the lot ready for what could be a new office building. Is it this one Curbed Chicago posted about back in February of last year? The one The Real Deal posted about in March? The one the Chicago Architecture Blog posted about in April? Cuz darned if I can find anything on my own. I can tell you that crane permit names Midwest Property Group as the developer, and Lendlease as the general contractor. And it looks like Pepper is the concrete contractor, so that would help explain their people and vehicle on site this week.

Here’s a dropbox presentation from Alderman Reilly’s office, shared in March of last year. Sure looks like a go to me.

I say, let’s go with the four above-named sources, and assume there’s an office building about to get started at LaSalle & Illinois in River North. Consider this my expressed written consent to start site prep. (In other words, tear up that parking lot.)
