Stair landing problem

[Tom Weir]

Hi all,
I have a short 7 riser stair connecting two levels, with a 6 foot landing that connects to the slab below. There are no risers below the landing.
The stringers are dog-legged and should extend the entire length of the landing. That's the problem. I cannot get the lower landing to work.
Presently I just have a slab at the lower level. I would like to get the stringers to work right. Attached is an image of the problem.
It does not seem that I can produce the landing with no risers below it.
Any ideas would be greatly appreciated.

Thanks,
Tom Weir
