Zoning variations have been approved for the mixed-use proposal at 315 South Jefferson Street in West Loop Gate. Pitched earlier this month, the mid-rise development is set to replace a small surface parking lot just steps from Union Station and The Old Post Office. Efforts are being led by a local developer, with Built Form LLC serving as the design team.

The relatively slim structure would rise nine stories and reach 109 feet in height, occupying roughly two side-by-side Chicago lots. The ground floor will feature a 1,130-square-foot commercial space on the northwest corner, along with a small lobby and a 22-space parking garage. This will be achieved by a vertical mechanized system.

The floor above will include a small fitness room, resident lounge, co-working area with private huddle rooms, and a modest amenity deck facing the building to the north. The remainder of the structure will contain 52 residential units, made up of 14 studios, 23 one-bedroom, and 15 two-bedroom layouts. The number of affordable units is currently unknown.

The structure itself will be clad in a mix of dark-tinted glass and reflective metal panels, with darker panels accenting the few inset balconies. While the total cost and timeline for the development remain unknown, approval from the Zoning Board of Appeals clears the project to proceed once permits are secured.

2 parking lots biting the dust in the same block! This area of town needs more infill. Bring it on!
Sometimes stuff like this is more exciting to me than super tall skyscrapers. We need more urban fabric.
Absolutely, well-said.
I couldn’t agree more, also because many of the high rises bring in the highest amount of new cars into an area, as backwards as that is for what makes for a great dense urban area.
Yes this is usually better, and in my opinion buildings with smaller footprints tend to be better for the feel of the city (or a large building with a bunch of side by side businesses, that can work too). We need this type of building all over the denser areas, not parking podiums
52 units on a side-by-side lots. great stuff.
52 tiny apartments with 22 parking spaces is exactly what people want. Way to keep people wanting to live in the city! How many of these dumb designs have to exist before people realize again that parking minimum laws weren’t invented out of thin air.
Well given how high the demand and rent growth has been in Chicago, that this building is literally steps away from downtown and the one of the busiest rail stations in the nation, and how half of the city’s housing supply pre-dates parking, I think they will be just fine…
You could have ended your comment after the first or second sentence. Do you think this building will sit vacant? I’m willing to bet against that. lol
Parking minimums are a cancer to our country. In a free market you should be able to decide how many parking spaces your land has. Either way, something tells me this building will sell out, and pretty quickly. It’s a high demand area, not just by Chicago standards, and there are a lot of people that don’t drive, or if you can imagine, some people can’t drive, crazy I know.
I’m really glad to see more infill projects like this near Union Station, especially with such a sleek design. Does anyone know if the fitness room or co-working space will be open to the public, or is it strictly for residents? Also, I was reading a discussion about urban density and sustainability over at guiadebetnacionalbrasil.com and it made me wonder if this building is aiming for any specific green building certifications like LEED?
