Hi,I was interested in this as i had been thinking of covering a steel shipping container in this on my property. I have just had a quick look on the internet and it seems that the berries are toxic, but might be worth you checking a few more sites than i have done. For me if there is any question of something being toxic I dont risk it. The building probably looks stunning covered in it, so personally i would stick a fence around it, just to keep both safe and save you alot of work.
