Making house

I have been pondering recently the mystery of a 'good house' (and i'm not talking about the physical building). What are the things which make a house somewhere you'd want to live?
Something that's really important to me is hospitality, although I'm not always as good as I'd like to be! What makes a house hospitable? What makes it a warm place to be and somewhere you feel comfortable?

Here are some ideas to be starting off with..

Values shared by housemates (e.g. hospitality)

Full part played by every housemate (rights and responsibilities)

Shared ownership (seems important but hard to define exactly what I mean.. something like 'we're in it together')

Meals together

Joint 'expenses' (food etc)

Welcoming guests - whoever has invited them

Decisions discussed together and nothing 'assumed' (tricky!)

I like to have housemates who look out for me and aren't afraid to challenge me when necessary

Any others?
