Hi, you have a nice space to start your projects. Do you need the built-ins? In the photo it looks like they are interfering with your electric heat, your air conditioning unit and they seem a bit flimsy and busy. If you don't have a large book collection, I would take them down. I would look at medium toned wood look laminates, not too busy. You have to choose something that won't clash with your tile and with your different wood tones - trim, the beams and kitchen cabinets wood tones. Definitely bring home samples to look at in you light and space. All neutrals have undertones and the undertones can clash.

I feel like this is a family room type look. But you can use as dining room if that works better for you Many will ask for more pictures and a floor plan. So if you can post those. But I guess to answer your question, if you do end up using this as a dining room: There’s not much room for much so a rug, table, chairs, maybe a bench on one side, what’s your style? Maybe wallpaper on the walls.

There is absolute zero need for a matched table. We have no clue the size of the room or the size of the table.......do we? : ) Show a pic of the existing space, some dining rooms you love as inspo pics too. What's your floor? Will you have a rug? What is around the room in other rooms? You haven't enough info to suggest....yet

Light Silver Sage belongs to the Blue-Green hue family. Technically a complementary color would be a color directly across from BG (blue-Green) on the color wheel. In Light Silver Sage's case that's the 'warm' side of the Red hue family. For example. want something more saturated and brighte. Everything I look at is to blue or green. Depends on what you mean by more saturated and brighter - because that statement kind of contradicts "too blue or green". Let me explain why I'm asking. Saturated usually means more Chroma, colorfulness. So more saturated is saying you want something bolder, more colorful and not as neutral as Light Silver Sage. Brighter or brightness is technically about lightness. So if you want something brighter than Light Silver Sage, it's going to have a higher Value and look lighter.
