Should dado rail follow floor or ceiling?

[joysexreno]

We have a hallway with uneven floors. Our builder insists that the modern way to handle this is the dado rail just goes straight across. He has installed it in this way, but will change the rail to follow the floor/stairs if we insist.

Nb: The rail for the stairs from ground floor is up very temporarily and doesn't angle as it will when finally installed.

All thoughts welcome!

@joysexreno now I can see all the photos & have re read the thread (several times!!). I wasn't too clear on what you meant, but yes, it should follow the skirting/ line of the stairs. Like train tracks!!

Yea I think with landing either side it should continue, to my mind that looks better and less fussy?

The dado should follow the handrails of the stairs
