Oh great font of architectural knowledge, point me in the direction of:

a) a building with an indepent roof system that is supported on columns that puncture the primary building structure

and

b) a steel frame building clad in pre-cast concrete panels that is not an office park, correctional facility, or medical center (unless of course someone knows of a beautiful office park).

There has got to be great examples of both these out there but I'm having a hell of a time finding them.

Thanks
