Hidden cork board for recipes, shopping lists, etc. More ways to hide the messy stuff - I love it! Can do more than one cupboard this way. Another idea: paint the inside of a cabinet door with chalkboard paint for grocery list, or pantry contents.
I love the idea of a separation wall with an inbuilt fire which creates a feeling of warmth throughout especially against the light, soft grey paint. It adds in a subtle way element fire to the white-grey (metal element) interior.
