Central Stairway

 

I've designed the stairway structure around 2 aquariums that will sit on the shelves.
It is a multi step process to spray the form, remove the form and spray another layer.

 
You can see the I-Beams that will hold the upper level catwalk from the main entrance to the stairs.
I still need to add the aquariums and put the new wood steps in, but getting a working bathroom is the next priority.
