Not sure I'd include 201 (former Ideal department store) in that demolition. It's a large 4 story brick building from post great fire that looks (other than the sketchy storefront façade) to be in good condition. Others on here have indicated the upper floors have recently renovated apartments.
Some interesting history about Union St here.
