Any ideas for covering opening from counter to dining room?

Do u want to block off from the wall to what looks like a set of burners? Shelves for spices and oils; wine rack; hanging bar to add hooks for pans and or utensils.

Fix a Blind on the Dining Side - Build a wall - Block it in by using a timber frame and lining it both sides. - Place a Picture over on the Dining side. - Fix sheet of Perspex (Plexiglass) over it. - Panel out the Dining room wall. - Add a window.......................

How about a mini barn door? That way you can still open it when you need access plus it's really trendy right now. Or (perhaps less trendy) add small shutters.

You can make. Pretty tapestry art or CurtAimns

3d wallpaper from wayfair. I used this for the same thing. Turned out beautifully.

Use glass blocks

I would use plain bi-fold shutters and either paint or decoupage the side visible in the dining area. When closed, it will look like a piece of art but will still be functional when the need arises.

I would frame it in say 2x2" wood and drywall it if you don't want an opening. Cover joints with drywall mesh tape, apply joint compound, sand and paint. Apply a piece of drywall on the other side, and repeat the taping and joint compound of the seams. Then on the kitchen side I would apply some backsplash if you like.

It would make a good weekend project.

I had a friend who bought a house built in the seventies and he ran a grooved trim board on the top and the bottom and made his own panels to slide in and use for light storage like bills, a chalkboard, aluminum sheeting, or magnetic board! The biggest plus is versatility! Good luck!

I had a similar problem but did not want to block out all the light and fell closed in in the kitchen, so I took a bookshelf and put mirrors in the back and laid it on its side across the counter. I turn the shelf facing the kitchen so I could us the extra space and stenciled a design on the back you could turn it either way. If you get tired of it then you can remove it without problem.
