Leave the pine boards but 1/4" sheetrock tacked up over the existing pine would give one the option of later removing the sheetrock and exposing the original wood.

If tacking 1/4" sheetrock would work (also, not sure how expensive that would be or what your budget is) - that would be great.

You can paint knotty pine walls - I know someone who did that for some of the walls in their lake house. However - the walls MUST BE prepped correctly in order for it to look right. After properly cleaning all of the walls, you need to use the correct primer prior to painting over the knotty pine in order to prevent tannin bleed through.

" Any ideas of keeping it with some update? "

Context is key. Post up pics as they will tall more than words.

I love painted wood paneling but if you want to keep the wood, use all white decor and furnishings. I created two AI rooms for you to show concept. Funny how it even added captions as I specified magazine style photography lol.

Thanks! I updated with photos.

I installed pine throughout my cottage in Maine and promptly painted it. The locals were scandalized. I love it.

"There would be no turning back"............from what?

A somewhat confusing palette of a peachy beige wall to wall carpet, yellowish beige couch? , red wall in the distance, the 1960 iron railing? and the orange yellow of the busy pine?

I'd paint it white in a heartbeat, consider some LVP flooring, a big area rug!

Depends how much time is spent, and resources and the feel you would ultimately want to enjoy: )

Paint it and IMO choose a new wall color and apint the pine the same . Yes it is a PITA o do I use 2 coats of really good primer and 2 coats of paint no paint and primer in one it does not do the job. I cleaned all of mine before priming too. That carpet needs to go for sure so plan a wall color to go with new flooring

Decide now what you want your vibe to be. Unpainted to painted is a big change, but still leaves you with the wood shiplap sort of vibe. Drywall and that leaves a smoothness that is a different kind of vibe.

Anywho, however you decide to do that... it looks like you have an actual full ledge surrounding the room. I would still keep that in the current wood. I think it's a nice feature.

I like the pine, the way it is, but, it would also look fine painted, however, that carpet is the big downfall. I would choose new flooring, way before deciding what to do with the walls, and then try to get your furnishings a bit more cohesive. Then take a look again with the pine walls, and see if you still want to paint. You sound a bit undecided, and once you paint it, its painted forever. If you decide to paint, remember it will be a huge job. You need to clean the paneling very well, then, you need to sand it really well, and then, you need to paint it with an oil based primer with shellac base, or a very good sealing bonding type primer. Once that is done (and I would use two coats of primer with all the knots that are in knotty pine), then you can paint the two of three coats of paint.

agree with @cat_ky

as the lower level of your home, I would leave it, BUT remove the carpet and edit the furnishings... there are specific areas I would paint, but only after you get rid of the carpet.

It could be a lovely space.

I would not paint that pine at all. Least of the issues in the rooms as noted above.

No matter the prep there will always be tannin bleed through, just learn to love it and paint.

I agree the whole color scheme of the existing room is out of whack, making it not just a knotty pine problem.

I like tracefloyd’s inspo pics for going in the pine direction , but then you need a new sofa, no carpet. No to existing carpet either way. If you’d use darker upholstery, it’d give a way different vibe, but would depend on the flooring and accessories.

So I think it would be worth some time with more color palette thinking. I find it useful to search for pics setting different parameters for walls, flooring, colors— just as a way to get some inspo about what’s possible. Or of course some kind of room visualizer technology using your room.

You do need to think of flooring and walls together before leaping, because the pine will strongly influence what floors work, compared to if you paint the paneling or put up drywall.

You could keep the beams and the pine under the shelf/trim and paint the upper walls. You could easily install some trim on the wall without it. That said, I'd update the look by replacing the yellow sofa.

Keep the pine. Paint the fireplace. Get rid of the wall to wall carpet. It will have an entirely different feel in there. I'm often not a pine fan, but I really like yours.

Carpet is being changed to a solid color Luxury vinyl. I know the carpet is awful, thanks.

I will start with the floor for sure, I'm thinking of painting all the NOT knotty pine all the same solid color (too many woods) and take it from there.
