Tell me what to do with this space

It is in an attic space that was converted into “bedroom”. It is probably about 4.5 feet high at peak. Maybe 8-10 feet long.

We plan on ripping up carpet and putting in laminate wood or something similar. The rest of the room is probably going to be kids library/nook beds, or guest bedroom for now, or maybe daughters future bedroom (will be in downstairs nursery till old enough for stairs/ to be “alone”, currently not yet born).
