Perhaps Tucson's Oddest Building?

This structure - I'm not sure if it is a residence or an office - has puzzled me for years. Note the big columns in the front which flank a blank wall. There is a tile bench between the columns but it isn't a bus stop. The triangular window above the columns is mirrored glass. The front wall looks like it is made out of a cargo container. And what's up with the sort of scalloped roof line??
