Ancora | Building Up Chicago

A pretty yellow tower crane rises above Ancora, the first phase of the Riverline project from CMK Companies.

You can’t stop a development with a tower crane. You can’t even hope to contain one.

Riverline has one of the newest machines in Chicago construction. A pretty yellow one at that. And its first task is Ancora, the 29-story apartment tower at 720 South Wells Street in the South Loop previously known (according to permits) as “Building D.”

Perkins + Will designed Ancora for CMK Companies, and it will be the first of many structures erected in the Riverline project. There will be 452 apartments and 246 parking spaces included with this phase. Lendlease is taking care of the heavy lifting.

Caisson work for Building B at Riverline is underway at 720 South Wells.

Everything has to be massive these days. Now you know that. Granted, some of the things we’re all referring to as “massive” lately are quite large, but we’re about two days away from ruining that word.

Anyway, the quite-large Riverline development CMK Companies is building along South Wells Street, in the lot just to the north of River City condominiums, is in full caisson mode these days. Case Foundation crews are out in full force, with the usual array of tools and equipment, drilling holes into the earth that will eventually support the weight of “Building D,” as the first of five phases is affectionately known. Per the permit on file, at least.

Building D will get Riverline started with a 27-story residential tower, containing 452 units and 246 parking spaces. It’s a design by Chicago’s Perkins+Will. Lendlease is the general contractor.
