Tell us a bit more about your art, rug and furniture preferences. I’d consider matching the white to your kitchen cabinets (nothing worse than mismatched whites) which would create a peaceful base and then amp up the texture with furnishings (and the people).

Thanks for your reply. We mostly seem to like wood! I've attached a picture of a rug that seems to go with it all but not sure we love it, and some other unstyled things about the house we like.

Dulux Natural White would be a good base. Ditch the rug, it adds nothing to your eclectic pieces. Try a faded vintage Persian instead. Add some more artwork on canvas which will add texture and colour. Consider swapping out the leather chairs for fabric.

Agree with bigreader, swapping the chairs for fabric would look beautiful with your table, textured rug, an irregular shaped pebble mirror above console , table, starting from the floor up add texture with furnishings and precious items, add gorgeous lamps to tie it all together.
