Oh wow, you've definitely been able to show creativity within brutalism. I also have been wanting to go and snap a few brutalism images of our buildings. Ours are no where this stylish.
We have ugly concrete buildings, I guess this goes to show that brutalism can be creative also. I'd image the insulation would be nice and cool in summer and warm in winter.
Thank you very much for your comment, @melbourneswest. I look forward to seeing them.
