Sounds like you have something rare and valuable.

Anyway, you make good points. From the point of view of society's health, it's good to create connections between people of different points of view, and this project could end up being harmful if it cloisters likeminded folks together. I would guess that many of the properties listed (such as being a musician or enjoying hiking) cut across fairly wide swaths of society, however.

i want to live in such a complex too.

I live in a mexican neighborhood and I see them talking to each other on the street but my spanish is bad to follow the conversation at their speed.

Just keep at it! When I first moved to Japan, I couldn't have a good conversation with anyone. I eventually met a young woman with Downes syndrome and she kindly chatted with me every time she met me. It was such a huge help! There was an older woman who would see me gardening in containers and come over to give me advice. I couldn't follow what she was saying at all, but she kept coming over and chatting anyway. I kept going in to corner stores and chatting with the staff -- nothing too long. Just a few sentences each time. I went every single day (even now, I know all the staff of every convenience store in town!) Eventually your language gets better and better and better. There is always someone who is lonely, or kind who you can chat to :-) Just keep smiling. Keep making contact. Say hello to everyone you meet. Every day try to have a short conversation with someone. You'll eventually find people who will be happy to chat with you in Spanish.
