What about mosaic tile? Lots of colors, styles, sizes, and finishes to choose from. You can also mix tiles or keep it simple and uniform - whatever you prefer! This fireplace was done in a single color of iridescent tiles, very sleek and modern! (other colors available!)

Greys would look good in these rooms. I wouldn't paint the paneling. Rather than a mirror over the fireplace a large scale painting would look good.

Hi everyone, we have moved in! We didn't manage to paint before we moved and think we will go for a staged approach - above the wood panels first in a warm white then decide on the panels. I'm having a bit of trouble working out what kind of sofa to buy and how at arrange the lounge. All furniture except coffee table temporary in photos and would love some ideas!

Yes.. I think you should paint, but... Why not lime wash the walls so you keep the look of timber and get the light, on trend Scandinavian aesthetic. I would go for a very light grey tint with a bright white ceiling and trim. Your fireplace and the deer would be great with this look: a rug and some white and grey cushions of differing textures would bring it all together. Coffee table candles would complete the Scandinavian look. Great room by the way!
