With that Instagram photo, One Bennett Park  posted a selfie and announced last week that Lendlease crews have reached to within five floors of topping out the 69-story residential tower.

The Related Midwest project is combined design of Robert A.M. Stern Architects and GREC Architects, bringing a mix of 348 apartments and condominiums to the Streeterville neighborhood. Completion is scheduled for 2019 move-ins, so there’s still a lot of work to be done. But topping out soon will be a big milestone, even if it means the beginning of the end for One Bennett Park’s two pretty, yellow tower cranes.

Sometimes I just stare at this one. So pretty. Enjoy One Bennett Park’s progress as of October 31.

Remember when we last visited One Bennett Park? Of course you do, because it was just last week. But that was during the day. (A sunny day; the best kind of day to see it.) This time, let’s check it out at night, which, before we know it, will be at about 4:30.

Sorry, I just depressed myself. Yay, Chicago winters.

From Grant Park, you can see the growth of One Bennett Park, now 50/69ths of the way up.

Related Midwest announced this week that One Bennett Park, their 69-story residential tower underway in the Streeterville neighborhood, has reached the 50th floor, nearly three-quarters of the way to its ultimate 69-story height. Chicago Architecture Blog had the press release yesterday.

One Bennett has been a marvel to watch, with all that yellow form work and blue wrapping. Dual tower cranes doesn’t hurt its curb appeal either. The joint design of Robert A.M. Stern Architects and GREC Architects brings a mix of 348 apartments and condominiums to town, slated to be ready for the moving vans in 2019,  plus a new public park (Bennett Park, of course.)

As appears to be today’s theme, Lendlease is the general contractor on this project.

And now, some distant views of One Bennett Park’s 50 floors of progress:

Maybe file this one in the “not surprising news” column, because if there’s one thing you can count on with 69-story towers, it’s that they’ll grow high.

One Bennett Park continues to do just that in Streeterville. How do I know? There are two tell-tale signs of tall buildings. First, the more it hurts your neck to see the top, the taller they are. Second, if most of your progress photos have to be in portrait mode instead of landscape, then you’re looking at a relatively tall building. It’s science.

One Bennett Park, the mixed condo-and-apartment skyscraper from Related Midwest, continues its rise into the clouds above the Streeterville neighborhood. The two-crane masterpiece by Robert A.M. Stern Architects and GREC Architects is approaching the 30th floor, on its way to 69 stories and 348 units. That’s Lendlease out there getting all that work done.

Bennett Park will be a thing in its own right, but there’s just too much construction going on with the tower for the park to have started looking like a park yet. Unless you mean a place to park construction equipment and material. Then yes, it’s a park. All in good time, though: One Bennett Park isn’t expected to open until 2019.
