The developers either need to commit to the Burnham expansion plan (blend with the Art Deco base) using quality materials, or go all out with a thoughtful, modernist design (tastefully contrast with the base) ala Hearst Tower. But don't make some piece of crap then paint it beige in the hopes that no one notices it.

Another option is leave the station alone, and simply build the adjacent tower on the Union Station Transit Center on the south side of Jackson.
