You could do either, but pretty generally they're laid horizontally. I guess the question is, would you rather the space feel taller (vertical) or longer (horizontal).

We built a vacation home in the woods and installed the pine ceiling on a diagonal - it accentuates the height of the 2 story great room and I think it's more interesting.

I couldn't find a photo to post.

Hi there - great bunkie. My personal preference would be to do it horizontal (like the ceiling), but you could go either way I think.

Will the floors be pine too? I know that all pine is the tradition for bunkies, but it might get a bit 'heavy' looking if all three surfaces are pine. Even just one white surface, like the wall in Annie's picture, might lighten the place up. Unless it is only used as a sleeping bunkie, if so, not a big deal. Given your use of the word bunkie and the look of your site, I'd say we must live pretty near each other!

Good luck.

My sidewalls were done horizontally and my ceilings were done vertically. Everone liked the look but past owners used alot of nails and screws which left holes so we covered it up with sheetrock. Since your siding is horizontal it might make more visual sence to go that way for the kick wall.
