Chicago-based Structured Development is celebrating that its new all-affordable condominium building, The Seng, is more than halfway sold out, with 20 of its 34 below-market-rate homes closed or under contract. Resident move-ins are now underway.

Designed by Chicago-based GREC Architects, the five-story development at 869 W. Blackhawk Street is the first all-affordable condo building of its kind in Chicago. It is one of three new residential communities in Structured Development’s Wendelin Park master plan, which includes a mix of affordable for-sale, co-living and market-rate rental housing. 

The Seng offers two-, three- and four-bedroom units for income-qualified households earning up to 120% of the Area Median Income (AMI). Buyers also must be preapproved for a traditional, FHA or VA loan and be certified through a homeownership program administered by the Chicago Housing Trust. The Seng gets its name from Wendelin Seng, a German immigrant who founded a namesake furniture manufacturing company on the site in 1874.
