Hi Patricia, Thanks for commenting, we want to do two walls one wall is in front of stairs and is 11ft x 8ftH and the other is a half wall 10ft X 5ft H. Similar to what is pictured below.

You could check out Architecture Depot online.

Architecturaldepot (sorry)

thank you, I will!

You could stain with something dark like Minwax Jacobean. We have ordered wood online before from BAIRD brothers. https://www.bairdbrothers.com/

hi J Mig, did you have a good experience with BAIRD?

Excellent! During Covid, my husband rebuilt our bed, because we upgraded to a king size bed after lots of years of marriage. He did not have the time to do all of the planing and sanding of the hard maple, and he ordered it planed and sanded. It was great to work with. Obviously there’s a trade-off when you choose to have them do that kind of work in terms of cost. And time.. But it worked for us at the time. We would do it again.

You could potentially use our wood slat room divider found here, feel free to reach out with any questions! https://andorwillow.com/products/wood-slat-room-divider
