The mezannine that I can see from my living room has about 40 square meters (430 sq ft) of space, out of which maybe 8 sq meters are livable. The rest is under the decreasing height ceiling. On the livable area I was thinking to create a mini cellar, where I can put a couple nice looking wine fridges, a wine barreI own, and a piece of furniture for glasses and liquors. But for the rest of the the space, going down from 1.2 mt/4 feet to 60 cm/2 ft. I would like to use as storage, or maybe books? I am out of ideas - shelves? Close it down? Thankyou for ideas
