I would do row housing and create small streets, personally I am fond of Spanish architecture and the haicianda you see around California and Mexico. I'd prefer to build them in such away that they are tightly packed but with open walkway's and courtyards. I am not fond of the white picket fence, every house has a yard and is separate sort of style.

I think a major problem is that people are so detached and alienated from their neighbors that people feel comfortable being that sort of loud jack ass. If many things are communal, like a communal rec. area, communal pool, heck even a communal big dining hall, people don't just get to know one another they also are likely to be more respectful.
