model with stairs

MODEL 1:
Stair one : 
   For the special space of the below ground, i think the circle stairs relying on the walls are more convenience for taking the model to the gallery from the under studio....

Stair two:

i am much more interested in the spiral stairs,so i experient  several kinds of spiral stairs

The whole view about the two stairs....

MODEL 2:

                              This word"believe"which i interpreted in different way stands for the religion always guide people with a mind of keeping peaceful to everything, no sharp point to the world, so "curved shape" stated this meaning....

In this whole space ,i tried to use two kind of spiral stairs. one stair inspired by the DNA chain, simple try.....

STAIR ONE :

 
                                        upper view

 Stair two:

                                                     
                                                             this is used in the below space.
                                                             DNA-TWO SPIRAL

                                But this stair is used from inside to outside...

Extra one:

                                                this one is diferent , but i have not use.....

This is all i try ,but i think something is still missing , keep going ............,xixi......
