Yeah I feel ya.
For me, I've got rid of most of my 1/4 scale stuff to make room for these Batman pieces.
I haven't got any kids either, so I've got a spare room and an attic that are for my 1/3 Bats collection.
Nice! I do have a spacious 4 bedroom home with a basement (unfinished). However, I also have a wife and 2 growing boys. If I ever get around to finishing my basement, I'm going to make a dedicated statue room for myself. The only trouble is that I keep ordering statues instead of putting money aside for the basement.
