...will be raised to 60". It will be a platform 8' × 4' (or, perhaps just a few inches wider to fall in line with the pocket conforming to the current set of stairs). It will provide a full landing with room for the freezer. I don't have CAD software; LibreOffice Draw is all I have to make a quick sketch (at right).
Later, when I'm old and broken, the freezer can be relocated back to where it currently sits and an elevator installed that will open to the garage floor at the bottom and to the landing at the top.
There will be plenty of access underneath both the stairway and the rest of the platform to store my triple fuel generator and a lot of other crap.
None of this is outside; all is in the garage and there has been no history of flooding, water, etc.
Standard 2" pine construction lumber of...
For vertical posts as needed I plan on standard 4" × 4" posts.
To make life super easy, I'm going to skip being a real man who builds his own stringers and railings. See below.
Joists 6 2" x 6 "x 8' Ledgers 2 2" x 6" x 8' -------------------------------- Total 8 2" x 6" x 8'
2" x 10" x 40" x 7 treads = 280" or 23.5' = 2 x 10' (6 treads, each 40") + 1 x 4' (1 tread, 40" minus 8" waste)
The outside dimensions are basically 5' × 6' and I can make it any width I want, but I'm thinking of a 3' stair width unencumbered. These stringers (one pair) with 2" × 10" pine treads are rated at 3,000 pounds. In my case, they'll never have to endure any load like that. They run $140 on Amazon.
We'll see during construction if a pressure-treated shim mounted under the stringer ends against the floor will be necessary to fudge the finished height of this stairway.
This handrail runs $114 on Amazon. I will need another, much shorter one at the end of the run where it meets the floor, but I won't really understand how long until after the build.
