While I was walking in my neighborhood I saw two examples of nature taking over buildings so as it is really relevant with the program of my building I decided to see if it looks better or not after all.
As those two buildings that I found are not that special and have not really detailed architecture I like that nature is starting to grow on them as it gives color and life on something alive. However I believe it is the building itself that makes the difference. I mean that in that situation I prefer the combination that nature creates to the building whilst if the building was really beautiful with unusual architecture I wouldn't prefer nature to "hide" that.
That made me conclude that people who are going to visit my building can be people who want to learn how to grow plants on building elements and people who want to avoid that.
