What size bed are you looking to put in? If it is a larger bed, I'd put it on the wall to your right when you enter. If you put it on the wall facing you, it can be over powering. Also, It can be centered between the windows for a nice, even, look.

Also, does each line in the floor plan equal one foot? Because if that is yes, this room is huge and you can probably do anything you want, and it wouldn't feel crowded! lol. If it is that large, a few chairs would be nice infront of the large window next to the washer dryer as a studying area looking out to what ever view you might have out the large window. You can add some floating shelves for an airy feel.

What do the green squares represent ?

Dear all, I remove the closet which is original at the nook, enlarge the window for the view, now I need some kind of wardrobe , this green are is for that purpose, what do you think? I may not draw it in scale, Measurement from A-B= 13.4 feet; B-C=11.4, C-D=3.8, C-E=6.4. It is not a big room.
I plan to have a full or a queen bed for this room. Floating shelving is good idea, may be that can be on the left hand side of the nook, BTW my husband plan to build a window sit for this nook.
Besides the bed, what else can I do? if the bed bw the 2 windows, what do I do with the wall facing me? a mirror to reflect the outside light from the window? what should I do on top of the head board bw the two windows? Thank for sharing your ideas.
