Jealous of both the size and the cleanliness!
Mine, IF you can see the walls for shelves and what is on them, with the ceiling, was painted gloss white.
The idea was to reflect as much light as possible.
One day I ought to clear the floor and sweep up all the swarf, dropped nuts, and washers from under the plastic matting.
So much stuff in there after nearly 22 years that a repaint will require an act of parliament!
