Hello Everybody

I'm trying to find out where or in what book Bucky talks about "Basic Maximum" living standards. The idea being that noboby would be really happy in a basic minimum house. Nor should we want to all live in gigantyic palaces. What we really want - and need to design for if we what a sustainable environment - is a basic maximum standard of living: more than just enough - but not excessive.

Does anybody know where Bucky talks about this? Thanks...
