OPTION 4: This is floating stair case
where tread is of toughened glass 25mm
thick supported by l channel of 40*40*2.5
mm on both side of tread an in one side
vertical steel support the steps as shown
in fig.

For second flight, tread is made
completely floating by hanging them by
steel and connecting those steel to the
slab each tread will have two hanging rod
in either side.

LEARNINGS :

I was completely bounded to typical RCC
doglegged and open well staircase but by
this time I got to know that there are
various technique of designing and
supporting staircase even toughened glass
and withstand as a support for tread.
