I’m moving to a bigger place and basically stressed out because I’m worrying about how to manage my two bunns and stairs with a floating hallway. As you can see, it will have spaces easy for them to slip through on the rail guard.
I’m in a carpeted one room apartment right now that’s single story that was easy to bunny proof. In the new place they will be living mostly downstairs on stone flooring (with rugs everywhere to prevent arthritis and foot/joint problems) and have access to an enclosed back yard but one of my bunns wants to be with me ALL the time (maybe even more than his sister who he adores) and follows me through the apartment I have now; it will kill him to be totally separated from me if I’m upstairs. He’s the one who gets upset/mad at me if I’m away from home too long. <3<3<3
My goal is to allow them to climb the stairs under supervision but somehow enclose the side guards. One side of the stairway follows the curve against the wall.
I know he’ll be curious and want to climb up and his sister will want to copy him. The stairs lead up to a floating hallway (with the same rails with spaces on the sides) – falling from there is a 15 foot drop down to stone flooring. 
Needless to say, I think if an accident happened and somebunny got fatally injured, I would seriously DIE inside and have to be in therapy for the rest of my life!
There are a couple of SIMILAR photos of what the place would have that I pulled off the internet; the rails would be wood and very similar looking and spaced as the photos with a space where somebunny could hop out to their death.

Anyone with stair advice? Or understand bunny psychology/behavior while climbing stairs?
THANK YOU FOR ANY ADVICE!
