Call me crazy, but I’ve had this thought about a lot of “boring” architecture. Why don’t we just say it’s an open graffiti spot, so that these large boring walls turn into something colorful on the outside? It’s most likely only gonna be as high as you can get a ladder, but I feel that’s better than nothing. Some people will certainly spray profanities on it, but graffiti spots already exist in some recreational areas, and those bits tend to get sprayed over by someone else, whereas more beautiful sections tend to remain far longer without being touched.
