Made from an old wooden box to house some bits of furniture I had accumulated (now how does that happen?).
I Briwaxed the floor, painted the walls and ceilings off-white with a water-based paint and gave the room a dado using a human-scale Art Nouveau border.
The room is 37cm / 14.5" wide, 23cm / 9" deep and 27cm / 10.5" high.
There are some splits in the wood of the box, which I just left as they are. I have no idea how old it is.
