If you can install that kind of combination stairs.
Just use that spiral staircase
pay attention to
Do not use wood.
Try to be metal and plexiglass.
Don't just listen to others put a screen between the gate and the stairs.
Make a partition or something
Because your door is in the middle.
The stairs are backward.
If you make a partition or screen,
It becomes a game with four walls surrounded by a piece of wood.
Be sure to remember.
Never!
I don't know where your door is
But you have a fish tank.
(regardless of size)
Then finish the stairs.
There should be no taboos.
