New building model -

This is my sketch. I did this with a star shape, I hope it's specail and you will like it.

The undergound sketch is abstract, when I draw these shapes, I just try to make the different spaces together. And hope you can understand the structure inside the underground floor.

And this is the underground stairs:

I got some problems when I make the stairs up the ground. Mayde I don't need the stairs anymore..actually I want to make the stair on the top...Anyway,

I try to think about a new way to build my stairs and make it looks together..I just wondering if it's ok?
