We don't have a lot of great brutalist buildings here and they tend to get a pretty bad rep, but we do have the Kane Building at my old university which is'nt too bad! It was built around 1968

I believe at one point it was rated as Ireland ugliest building (at least that's what everyone said) - I really don't agree! I've always found brutilast buildings to be very comforting particularly the interiors and the way they use light, air and texture to create atmosphere. I always felt much more comfortable going to classes in the Kane building.
I took this picture of the stairs there and I still think its one of the best pictures I've ever taken

As an honorable mention, the Glasgow School of Art library where I did my masters was also a lovely building to be in, although it does not quite come across in the pictures. I also could not find any interior pictures - I dont think its very loved, or at least its overshadowed by the Mackintosh building that is much more famous (for good reason admittedly!)

Glasgow had a few nice ones I took pictures of!
