I don't have this one any more (the weather finally killed it), but in its time it was the smallest known Roll-Off-Roof Observatory in the world.
It was 1200mm x 1200mm and 1200mm high.
It easily accommodated my EQ6 mount and ED80
A pic of the inside and here is a
'You Tube animation' of my son Aaron opening it up when he was only 11 years old.
and here is the original thread about it:
