    Default Two stair flights with slightly different sizes.

    Say you had a staircase consisting of a flight of 8 stairs, then a landing, and then another flight of 8 stairs. Say the height of the risers on the lower flight is 175mm, is it within the rules to have the height of the risers being 182 on the top flight? Imagine the staircase conforms in every other way, and the variations between the riser heights within each flight is minimal.

    We may need to modify our staircase as there is an issue with one riser, and this configuration may be the easiest solution.

    My understanding is that the rules on riser sizing apply within a FLIGHT of stairs and this configuration would be allowed. Am I right or wrong?
