It has been many years since I have seen that building up close, and it wasn't much better back then. But at least then there was a real company running a real business in it.
We have several customers in the Berne area, I will try to ask one of them this week if they have heard anything. If there is any remodeling going on there, one of them should be involved as a sub-contractor.
In case I forgot to mention it above, Always Just My Opinion
