Details have been revealed for the upcoming mixed-use development at 4100 W Belmont Avenue in Irving Park. Located at the corner of Belmont and N Karlov Avenue, on the southern edge of the neighborhood, the proposal would replace an existing one-story commercial building. The project is being led by a local businessman under the entity Belmont Karlov LLC.

Once again, this project is being designed by local firm Hanna Architects. It will rise five stories and approximately 65 feet in height, with a total of 46,500 square feet of space. The ground floor will include 2,000 square feet of divisible retail space on the street corner, a small lobby, and 22 parking spaces split between two small garages accessed from the alley.

The upper floors will contain 32 residential units, all configured as two-bedroom layouts. Unlike other recent developments, the units here will not feature any internal (windowless) bedrooms, and each will have a private inset balcony. Of the total units, seven will be designated as affordable.

Topping the structure will be a small shared rooftop deck. The building will primarily be clad in brick with metal accents, though final color selections have not been determined. The project will require city approval before proceeding. At this time, no timeline or total cost has been announced.

  1. Does Hanna have kompromat on all the builders in Chicago? The work rate is unbelievable for such a large city with what should be steep competition.

      I’m not a Hanna hater–they provide a service the market demands–but I, too, have wondered how they are able to get so much market share. My guess is that they are experts in code, zoning, etc. and assist developers in that way. And they own a quarry that extracts brown clay for bricks.

      • I have some direct experience with the developers that use Hanna. A significant portion of the UA building community uses Hanna; in general the UA builders prefer to work with a close knit set of associates. As far as I can tell he UA builders still dominate the smaller scale infill projects in the city such as this one. Some UA builders are now into the second generation – the sons of the original UA immigrant wave that happened decades ago. In addition it’s been my experience that Hanna is not involved post delivery of the permit drawings which are then used for construction. There is no additional “construction” set of drawings as a deliverable and Hanna is out of the picture during construction. This keeps the cost down but also allows the builder more flexibility during construction.

  2. Why are so many projects four and five stories rather than seven ?

    And that begs the question : Why is the City Council opposed to buildings 12 to 20 stories ?

    • There are pretty drastic code changes once buildings hit 60-FT, at least in the MEP world. I have to imagine there are similar implications among other trades.

    • Ok, yeah it’s technically Irving Park, my bad.

      • I live in this part of the Irving Park community area, & it really does not belong with the rest of it at all. Then again Pulaski & Belmont make it feel cut off from the Avondale, & the only way it belongs in Hermosa is if you put everything west of Pulaski from Addison to Fullerton in Hermosa as well.

        A great example of how neighborhood boundaries end up being much fuzzier in many cases (even when a railroad viaduct is cutting through it).
