How to make landing wider than stairs?
My stairs are 100 cm wide but landing should be 120 cm.

I tried it in edit mode and in floor plan it seems that I have manualy made it wider but in section there is no landing.

The Stair body's extents are defined by its Boundary.
Select the Stair Boundary and edit that, the geometry will follow its new shape.
