Lucia's bedroom
Built in double bed with draws or a pull out bed underneath, then a small bookcase and desk. It would run along the wall by the window. That wall is 3200. A double bed is 1880 long so the book case and desk would be the remaining 1320. The desk and more shelving could go around the corner. Then rest of the space is for sitting. The width of the room is 3000 and a double bed is 1350 so at minimum you would have 1650 for sitting.
This one drops down and clicks into place.
