Small stairs with landing

stymie222

Just about finished with my project. My new garage was built along side my existing home. I need to build a small set of stairs from my garage concrete floor, to my kitchen door.
From experience, carrying groceries and looking for keys leads me to want a small landing at the top of the stairs, rather than just a last step. The landing could be about 24" wide or a bit smaller.

From the garage floor to the bottom of the aluminum threshold of the kitchen door is only 23 1/8".
I have seen the calculators for the stringers and such on the web, but nothing about integrating a landing with the stringers. Since this is such a small rise, could I use some type of "Box" design, rather than cutting stringers?
Thanks any links,diagrams or suggestions wecome.

Unless this stoop in totaly under cover you never want a stoop or step to be even with threshold, water will get in under it and take out the subfloor. It needs to be at least 4" below it.

Totally under cover in finished garage.

The landing needs to be 36" wide not 24".

Inward or outward opening kitchen door?
Three individual boxes....
1- 36" x 48" x 23-1/8"
1- 36" x 22" x 7-23/32"
1- 36" x 11" x 7-23/32"

Thanks-

36" Exterior door opens into kitchen, will not swing out over landing. Yes- 24" deep not wide. sorry

Willie T

Then you can shorten the length of that 48" box some if you want to.... although I wouldn't unless you are cramped for room.

Thanks- Looks like plywood is the only way to go on that rear box. 2X8's for the fronts.

Any sugesstions on the back box interior and center framing?

Willie T

Just brace up the corners of the plywood box with vertical 2x4's on that big box, and on both the 22" and the 48" one, run a few 2x4's across to support the tops of the boxes when people stand on them. The 11" one needs nothing.

You could probably get by with no bottoms on any of the boxes.

I built 38 triangle pieces like shown here for a stage, 10" high as I recall, out of 3/4" plywood, and only braced up the three inside corners.

This was about four years ago, and the stage has been used by a bunch of teenagers several times every week since then. They are all still as sturdy as the day they were made

Thanks for the help. I don't have to use 2x8's. But I will have to use pressure treated ply because it will be on concrete. Those sheets are always twisted. What ever corner bracing I use will also have to be PT.
Since this will be a little over 3 feet wide, would vertical 2x4" bracing at the tops, be adequate for the center braces ?

Willie T

The tops need only 2x4's on edge.... on maybe 12" centers across the spans.

My triangles use no top support other than the plywood.

PT is not needed if you simply tack or glue a waterproof strip of some kind on the bottom edges. I also recommend cutting the sides a little high like the triangles to help keep them from rocking so much on uneven concrete.
