The top one is a development from the bottom one to bring back the element of going from one side and shifting to another within the shop. Where ive highlighted blue (underneath the landing) on the 2nd drawing could be an entrance to the open kitchen where the Patisserie staffs could get in and out. And the strips do not go right up to the ceiling but merge into one surface.

I think i quite like how there could be the entrance underneath the stairs but may be it does look better when the strips continue right up to the ceiling (bottom one) . And may be add more strips to the landing part so the whole form looks more connected. Pls let me know what you think of the revised design.
