Execute the commencement of an existing reinforced concrete staircase?

Hello everyone,

we currently have the following question. How should we carry out the step of an existing Steuerberater.-staircase? I have sketched the situation and attached it. Ideally, we would lay the floor covering of the floor slab on the step, of course without a joint. Now the question arises for us whether it might become a problem if the floor slab lies "floating" on insulation and the step is on the Steuerberater.-staircase without insulation. What do you think? How can this be best resolved?

Hello, we covered the step with the floor covering of the story. However, this cannot be done without joints; both in the tile and in the linoleum there is a joint directly above the joint in the reinforced concrete. It cannot be done differently. The tiles continue seamlessly in terms of size but have an additional joint. In the linoleum, we have a joint analogous to the one in the doors.
