Stairs - Are the stair dimensions 2.00x2.00m okay?

Just by the way: How high does the staircase have to be? So room height + ceiling = ?

Standard construction height = 2.67m - 0.15m

For cats, risers are mandatory, I agree with that.

So if anyone here has absolutely no problems climbing the stairs, then it's my cats. On the contrary, they particularly liked lying at the edge and looking through the opening in all directions. However, we now have closed risers so that the hair doesn't flutter down like snow throughout the whole house.

Step stools for small dogs!

Standard construction height = 2.67m - 0.15m

Do you mean 2.67m total height + 0.15m floor? Then we would have a staircase that has to overcome 2.82m.

Are the floor plans in post 1 the current ones? Otherwise, please upload the current floor plans or link or name the post where the current status is included.

I had already written at the very beginning that our staircase is the same size. I don't have any pictures available right now, but it looks approximately like this: Optima Pure Color Buche keilgezinkt
