Is this a new build, an addition or a reno? Will there be TV in this room too? The right end floor plan looks a bit confused, and makes me think you are adding on to an existing home. Are those doors or windows that would flank a FP there?

@decoenthusiaste it is a Reno. Originally that room was an addition that you are referring to. Good eye.
They are doors on both sides that would flank the Fireplace. Door on the left side if facing the fireplace and a opening to a small hallway leading to the master bedroom on the right side of the fireplace.

There will also be a tv in that room. So basically the tv will go the opposite spot of where the fireplace goes. Although it could go above the fireplace as the mantle really isn’t that tall. But I know people say that’s a no no.

The original spot for the fireplace was on the bottom, but the architect was suggesting moving it to the other wall, flanked by the 2 doors on each side. We just aren’t sure what to do. Taking into consideration the tv placement and area seating also.

And huge windows facing the East, which is the top of the picture

If you'd enjoy watching from the kitchen then put it TV on the end where it will get less glare from the windows. That leaves the FP where the A put it.
