Well...My boyfriend cut some of the squares out of a grid using big scissors (which was suprisingly easy to do) so that I could have my ramp going up to the middle of my top floor so I would cut squares out of a grid on the side and then use either a piece of piping (from a DIY store) or some bent grids covered in carpet or coroplast with towel over it going outside the ramp and up to a similar hole on the external wall of the upper floor. Sounds complecated but is very easy once you have the bits.

There is a picture of an external ramp on the photos but I can't find it.

Also I would hold the ramp on by using cable ties!

Hope this helps.
