What is the solution, though? The problem is that there aren't really better alternatives.

Given present market conditions, there are two outcomes- First option is the building is demolished for Penobsot parking, and the Penobscot is a competitive building with a future. Second option is that no parking is added, and the Penobscot continues to wither away.

Downtown Detroit office space needs adjacent [[preferably attached, with direct access) parking. Absent this amenity, the building isn't worth much, and usually eventually abandoned.

Obviously there are ideal situations that would both preserve the old bank building and allow the Penobscot to thrive. The problem is that none of these solutions are within striking distance of present reality.
