Do what I do, leave the bikes you dont ride all that often at somebody elses house... 
In my case, 2 road bikes (and until last month, 2 track bikes and assorted wheels) are at my parents house.
So, my shed just houses my 2 GT's, various spares on shelves, my 2 kids bikes, gas BBQ and the tumble dryer.
I can swing various cats in my shed
But, having said that, I'd glady shoe-horn the bikes in if I had your stock list
