There are "architectural" hints in some of the photographs that this is not the final finish. This is probably the inner face of what is known as a "rain screen". My guess is that the final finish will more resemble Gehry's Disney Hall in L.A. which was applied over a similar "rain screen" subsurface.
I know that I am probably alone in this opinion, but I personally really like what they did with this library, especially considering it is a renovation of an older building. Yes, I do think that they could have been more creative in the finishing of the building (such and adding different textures like stone or cinderblock patterns), but... I still like it nonetheless
@Platinum107, I am totally with you on this one. This will be a great addition to the so-called civic centre. The main entry promises to be very dramatic!
