To be honest I was underwhelmed by the interior. It is certainly nicer than what it replaced, but frankly I found it to have that character-less shopping mall feel that I am not sure will hold up well over time. If you compare it to the library in Calgary the Milner is inferior in every way (and I say that as a very proud Edmontonian).
Frankly, if it was up to me I would have restored and expanded all the beautiful mid-century styling from the original library. The furniture and wood on the second floor was so cool and exuded character. The real problem was the cheap and poorly thought out renos from the 90s, which we've sort of doubled down on.
At the end of the day, the new space is nice and will be better used than the old library, but I see this as a missed opportunity by the City, which seems to have been convinced by their architect to simply embrace the latest flavour du jour.
