I would close them in and hang one fabulous piece of art up there.It also would be good to see the whole space .

I wouldn't decorate the top two. I would either drywall over or paint them the same color as the wall in an attempt to blend in.

I would, however, decorate the lower one- paint/wallpaper, art/mirror, console table or shelving, etc...

I honestly never thought to cover up the alcoves! such a simple idea. lol!

I would either remove the dividers to create one large area to put in shelving for books or display, or as others have suggested, fill in with sheet rock to give a solid, smooth wall. As it currently is just looks strange and nonfunctional.

I have to admit, it looks nice in model homes where its professionally decorated. But not everyone ( including myself) can hire someone to do it justice. :o)

I totally agree with cawaps, and personally think they look a bit silly regardless. In a church or large public building where they may serve a function to have art without impeding traffic flow, I can understand it, but they seem totally useless in a private home IMO.

Drywall the top ones away. Build in cabinetry below. It can extend forward a bit past the opening if you need the depth. Here are just a few ways to consider doing it. Which one depends on how you plan to use the room.

Twig Sculpture

Bamboo or wood hot melt glued and painted

never seen those before. another good idea.

I wouldn't draw attention so high by putting anything in the alcoves, but I don't mind the architectural interest of the spaces if you just leave them empty, and decorate the area below them. I don't think it's necessary to fill them in.

They're too deep, too large, and in a strange place to effectively showcase art. I'd have them covered with drywall.

No you can’t put art there because you can’t see it it’s too high but you can put wall decor of some sort

I was originally thinking of installing hanging shelves and/or huge picture frames. but couldn't decide.

Art is not relegated to paintings and prints. I don't think sculptural elements will look right in those deep-set niches either, and would simply cover them up.
