The box is simple, just 6.5 inches square, made of 1/8 inch pine (or similar - not built yet) and only needs to support its own weight.  It's a purely aesthetic function.

btfdev, I think I like the scissor lift idea the best, as it seems the most reliable, cheapest, and probably easiest way to get the job done.

And now that I think about it, I had planned on using the 'lid' as the access panel, so the lift still allows that option.

Thanks for all the suggestions, and I'm still open to others!

Here's another idea:

The black lines are extra supports you need to build. You have a small winch (blue), and the string (green) goes over the floor supports, then connects on the bottom of the lid supports.
