^^ Looks very Walter Netsch, including the interiors.
@ Jibba, your question is a complicated one. All metal expands and contracts with temperature change. Various metals do this to different extents. Other than change in temperature, corrosion can lead to volume change (in steel possibly quite severe - check out the untended window frames on Alumni Hall at IIT some day if you want to see the results of this), but since copper patinas, you wouldn't expect a lot of change from this cause.
Ultimately, the architect and the engineer need to put their heads together to design the cladding so that expansion can be addressed and incorporated into the structure. On a simple structure, these kinds of solutions manifest themselves as visible expansion joints. If the structure does not allow for movement, you will possibly see buckling in the metal.
If you develop a keen eye for these things, you can see many failed designs (bridges, buildings, etc) that have problems due to insufficient attention to these matters.
