family room with a green room

Here is our family room. It has a "green room" as well which is kind of the space built by the first owner to have more plants or get in more light (not really sure).

Any ideas on how to utilize the green room or the entire room in general? There is mulch at the bottom in green, not looking to plant anything in ground, can do put some potted plants though

I also need to buy some light for this as there are no ceiling lights. Not looking to do anything fancy or spend a lot. Just want to know if can do something better than placing a lamp (or two) in the corners.

PS: The pics are old from the real estate listing when the room was staged with some furniture
