Does one large window look better on the exterior? I think it's clear that two smaller windows on either side of the bed work better inside (this is how my primary bedroom is), but what led the architect to draw it the other way first? You have to try to balance the exterior appearance with the interior requirements. Is this an addition or a completely new build? What style is the house? Do you have an exterior elevation you can show us?

[I'm not a pro] +1 to what kandrewspa said re: balancing exterior + interior when it comes to deciding on 1 large window vs. 2 smaller sides-of-bed windows.

In any case, the 4th image you posted looks like a terrific layout - the bed is *almost* centered in the room and not stuck to a corner, assuming you are aligning the "top" night-stand with the bathroom's "bottom" door opening, which I think is what the layout depicts (it can even overlap or partially overlap, I don't think it's a big deal).

Would also similarly work if you'll decide to do 2 windows instead:

What I like about this layout is that you have all the doors "busy-ness" at the "top" of the bedroom, close to the bedroom entryway, so the "bottom" of the bedroom stays "clean" bedroom area:

It may also be more convenient for you that the bathroom and WIC are close to one another (as opposed to the 2nd image you posted), as it nice to go straight from the shower to the closet (maybe that's the context for the "not really practical for movement around" argument).

Thank you for the inputs. Attaching a picture of the elevations plan. This is an extension and addition where there is no windows on that part. The crossed out one are being removed as the bathroom was moved to the other side and the front room already. We get blasted by the sun on the side most of the day. So we are planning on decreasing the size of all the windows on the bottom and especially since we are on the corner

What is the space labeled "FAU" ?

What is the space labeled "FAU" ?

Forced Air Unit, perhaps? https://www.reddit.com/r/floorplan/comments/1332gph/what_is_fau_mean/

"Forced Air Unit"

I never heard of that one. The immature nine year old in me wants to run with that one, but I won't.

FAU, is my furnace system. Moving it would mean buying a new system and redoing the existing ductwork etc. I was also told that there wasn’t much attic space that the left side of the home so.

Right now the furnace is open as it’s in the storage space. With option 4 any suggestions on doors because it will be there to the entrance of our primary and need some sound buffer. I was thinking of sliding doors to allow actual use of the storage space.

You didn’t ask, but can the attic access be moved into the middle of that storage space? You’ll likely have shelves or stuff in that corner. We have twice had the attic hatch above shelves, and you can imagine what a pain it is to get up there. Not that you have to go in the attic often, but when you need to, you probably want to get up there quickly.
