Got Yellow Poplar and Southern Yellow Pine...Which One, Or Both?

[Woodmonkey]

I'm planning to build a stick-framed cabin for use as a cook house. It will be 288 sq. ft. interior, and 144 sq. ft. covered porch. Other than a small bathroom with a toilet and sink, the rest of the interior will be an open floor plan. I intend to have a metal roof, but would like to use my own sawn lumber for the rest of the construction.

Other than the metal roof, is there other store-bought material I should use instead of my own air-dried lumber?

Should I use only poplar, only pine, or both? What species is best suited for what? I have way more than enough of either to build the entire structure.

My sawmill will be delivered next week, so I plan to start felling trees tomorrow.

Pine would be the traditional framing lumber choice.  Dries fast, too, just like the poplar.

Use Pine for all of your framing needs and the Poplar for board and batten siding.  You could use a combination of the two for your wall paneling and ceiling.

I used my own lumber for this project:  Cabin Addition

Yeah, I assume you're talking about regular Tulip poplar?  I've heard some people call cottonwood and silver poplar, poplar. 
SYP and poplar are fine for either.

MM, what did you use for "whitewash"? I used Permachink's water based interior white stain with their satin clear finish.  Worked awesome.

Around here it's commonly referred to as yellow poplar. Other names include tulip tree, American tulip tree, tulip poplar, whitewood, and fiddle tree.

It was not available in the gallon so I had to buy a couple of quarts.

This is also the whitewash stain that I used on the Cabin Addition walls.

Pine for your framing, poplar for your siding. That's what I'd do, anyway. If there's plenty of green heart in the boards, they'll last as long as you want. I've seen poplar boards around my neck of the woods nailed up 100+ years ago and still going strong.
