I live in a block of flats (apartment building, as Americans would say), and it is out of choice. I like having all that activity going on around me, except if they play sensory-intolerable house music, or talk loudly after 22:00 which is when the house rules say to shut up.
My nearest neighbour (the guy whose front door is opposite mine) recently became a friend, although we never chatted in the past two years. He's more than 20 years younger than I am, and he's enjoying the friendship because he has OCD and he likes to chat to someone who 'gets' him and for whom weird is normal. I also give him advice about his OCD because I have contained and chanelled my own obsessive compulsions to harmless activities for years. He has actually come to me to ask me specifically if he could come along when I go out with my aspie friends (we have a social group that gets together once a month). In 2007 I also had another neighbour whose company I loved, and we became close friends and have maintained contact after he moved.
Last year my head was in a really bad state and I hardly had visitors at all, because I couldn't cope with seeing people. Meldowns all the time, sensory shutdowns, relationship issues, anxiety disorder, ADHD turned half-psychotic, etc., etc. I had no friends in my building last year. This year I am better, but I do still have to ensure that I spend plenty of time on my own.
I wouldn't like to live in a different building, because where I live there is a lot of racial and class diversity, and that makes me feel comfortable, because there is not a great pressure to conform to specific cultural expectations. I like having friends, as long as they are not too normal.
