I have no direct experience but I have spent a lot of time thinking about how to realize my own dream of having an artist's residency -- which is actually a similar kind of thing, but temporary. I too am about to acquire the real estate, but don't have the rest set up yet. One unsolved problem I keep returning to is that the limits of the offer will affect who will come join you. Unless you can give people their dream lab and a ton of money and publication then some of the people you want, will not be able to come even if they really do share your vision. I think this is an inevitable compromise, but one that should be made very deliberately. Consider your dream researcher. Does she have a family? Can you get them to Germany on the appropriate visas with the mandatory health insurance? Will she have to quit her previous job? Can she afford to go without income for the duration of her research? If not, how much money does she need? What can her husband/wife do there? What if they have a child with special needs? Can they bring their three dogs? Can they be there three days a week? How will they get to Berlin? For my project, I plan to start very small, since I don't really know what I'm doing and don't have too much money nor time to dedicate to it yet. You might consider doing that too: make the place really nice and get some people there for a shorter period of time, and figure out your growth strategy after you've gone through the mini version with some researchers, and have properly digested their feedback. And put massive effort (and money assuming you have it) into promoting them and their work: the more it looks like Forschungszentrum Akhann is good for one's career, the more you'll have your choice of researchers. That, and take care of your liability situation. It's not so bad in Germany as in the US, but consider the possiblity someone gets sucked into the flux capacitor while helping you with your research and it's kind of your fault. You don't want to lose the whole institute over it, nor the personal fortune that has let you set it up. Definitely find a good lawyer with relevant experience. Good luck with it! I think the world needs more stuff like this.
