I have never been a big fan of incorporating facade's into a buildings designs it seems like most of them end up being not all that well incorporated (at least here in Austin).
Look at 300 N Lamar
I think they should have at least extended the colour pallet down the entire side of the building, It currently looks like someone superglued this weird facade on the side. I would have preferred to see a continuation of the design for the entire side. However, I could see how some might feel that by continuing the design, it might be not truly representing the historic character.
I am sure that there are other examples around town, but this is the only one that I can think of..
