Inspired by Cardinal:
Describe and, if possible, link pictures of the most poorly designed building(s) you have ever experienced. This includes the exterior aesthetics, building's relation to context, and interior functionality.
The Media Union on Universtiy of Michigan's North Campus.
This is one of those buildings with no primary entrance or at least the designed "front" is hardly the functional "front". And the interior is one of the most disorienting places in which I have ever been. The interior passageways radiate symetrically from the center of the building, but there is no obvious detailing to direct you to your desired exist.
Plus, there was too much wasted space in the interior, because of the unecessary use of atriums throughout the building.
