I built a crude stairway so that I could get up to the rooftop of my Twin Arches home. And it really is lovely up there, a great place to set up a balcony / verandah / relaxation space. Unfortunately there is an Invisible Wall all the way around, preventing me from actually getting onto the roof and making something of it.

I'm sure there are Complex Technical Reasons why this has to be... but if it's at all possible, I'm sure that I'm not the only nut in the bowl who would like access to that space!
