I really like what you said about living with people from other denominations. I wonder, though, what overarching frameworks should be in place? I think difficulties may quickly arise when Christians from different denominations live together. I think to answer, the ecumenical movement is a good place to look for answers. I myself have been living in such a setting and have enjoyed the richness of inter-denominational life, but it is important to be on guard to make sure that the spirit of unity is reigning!
