You contradict the purpose of an Internet forum by asking exactly these kinds of questions and hoping for experiential knowledge ..
What use are experiential values for such a question. It works for one person, doesn't for another. However, the planning architect knows the floor structure and should therefore be able to provide information.
I guess that's what it's about. His planning architect probably thinks that it simply doesn't work. If someone says "Yes, I have done it that way," he's already helped. Then he can ask for reasons why it doesn't work specifically for him.
