Horrendously difficult! You've got to make three curved panels - front, top and back - that fold inside each other. Side panels that were completely removable and just lifted into place would work OK - the 'lift-and-drop' sides from a child's cot would hit the underside of the top panel when you do the 'lift' part.
If you must have a lifting. curved roof, I would think either the Winter Warrior idea turned round or Sumner's parallel-lifting top would be less work.
Mike:
The gas strut just takes the effort out of lifting the top when the sides are in the way - it's hardly essential.
Don't understand the dimension comment - all drawings have marked scale bars on the bottom.
