I finally was able to stop by and see this wild project in person as I have never seen anything like it. This project started back in 2017 as a design then construction started last year. This 500 box affordable apartment complex is located at 534 S. 500 West SLC UT.
According to KUTV news, this complex will have 83 apartments with studios, 1 bedroom and 2 bedroom options. More information can also be found here.
