A few more local one in Lansing...
The Arbaugh was built as a department store, then turned into a state office building, and then rehabilitated as an apartment building (first floor commercial, underground parking) in 2005. It was coated in a gold glass curtain-wall hung pretty far from the facade, so the original facade was pretty well preserved beneath.

The Knapps Centre was originally built as a department store, turned into a state office, and is now underground preliminary renovation work to turn it into a mixed-used structure (company headquarters, business incubator, office space, top floor apartments, first floor retail and underground parking). The skin will be kept, though, they are trying to change the block glass windows, but not so much as to disqualify it for historic tax credits.
