The point I'm getting at isn't so much about who legally owns the land or the building. It's more to do with whether the local community feel that this new facility is part of their community or a foreign outpost that's nothing to do with them. If that sounds strange at first reading, yes I agree, but you'd be surprised how many development projects (schools, clinics etc.) end up decaying and unused simply because the local people feel distanced from them. People are sad when the facilities are lost, but feel that maintaining or reparing the facilities is beyond them, because creating them was also beyond them. In a sense, they're excluded from the process, and it's difficult to bring them in at a later stage when they weren't in at the start.
I'm not saying any of this is necessarily true for your project, because you know the details much better than I do. Nor am I intending it as a criticism, because the alternative path (to ask local people to contribute) is equally problematic for a dozen reasons, including the fact that many people are so poor. I merely offer it as food for thought. It's also a pleasant distraction from my work.
