Arabian villa enchance

[Leslie]

I have created a layout with this villa. Arab.mbp

It has the most completed interior but some cases displays outer space.

This is not an error, inner sights caused it. I kindly ask the developer @Jim Knopf  to enchance it:

make the steps, ceiling and inner walls on the middle floor:

 

and enlarge inner walls at basement to the ground level:

Of course not everybody uses inner sight so make it by variations.

Thank you, in advance!
