A developer from Richton Park, Il received permission last week to construct a three-flat on the same Washington Park block where they got a trio of permits back in June 2025. The Kolossal Group submitted an application on October 15 of last year for 5653 South Prairie Avenue, and that permit came through on February 20 with a reported cost of $500,000.

Short on details, the permit calls for a ground-up on-grade structure with three dwelling units, with an unspecified number of parking spaces on a concrete slab and fencing around the property. Back in June, permits were issued for 5637, 4641, and 5643 South Prairie, all with the same limited details. The three 2025 builds had reported costs of $450,000. The most recent Google Street View images from the alley show demolition fencing around those three lots. On all four projects, The Kolossal Group is the developer and general contractor, with Kathryn Shahbaz Obrien named as the architect of record.

Washington Park, Bronzeville, and Woodlawn have been seeing a surprising amount of infill. Would be really exciting if they all grew in population next census
I drove by the site not too long ago. The first 3 homes are practically done. One of them is even on sale on the Redfin app for $1M+. If they cost half of the cost to build compared to what they plan on selling these homes, I would say these are very profitable and we should continue to see more built.
