We need to see all the walls , we need to know your style and colors you like so much missing info. Waht exactly is a HD laundry ?

We need to see the entire room and let us know what furniture you intend to keep if that's the case.

Waiting for more information...

if the furniture and decor/styling is an example of what you like, I would not wallpaper.

You already have enough visual activity going on.

A wall of wood might compete with the wood pattern on your furniture. It is already a dramatic feature in the space. Photos of all four walls, measurements and existing furniture placement would be useful in offering suggestions. Will you be repurposing all the existing furnishings, or replacing? What colors are you hoping to include?

Why a buffet in the bedroom or somehwere else on one of your walls?. We need a lot more info , pictures and even a to scale floor plan
