Struggling to decide on window arrangement

[DecorDilemma]

I had a previous thread seeking opinions on how to do up my living room (https://www.mumsnet.com/talk/property/5161849-how-would-you-do-up-this-living-room), and am now at the point where I need to decide on what windows to have in the bay.

There are two main designs I'm considering:

1. Have just one large pane in each of the four sections to the sides of the doors, and make the two panes above the doors into top-openers.
2. Keep the horizontal "divider" between top and bottom sections going all the way around, but remove all vertical dividers, and just have one pane of glass in each of the remaining sections. Make the two top panes on the angled walls into top-openers.

I've attached a night-time photo of the bay as it currently is, plus professional mock-ups of both the designs I've described, and dodgy photo-edited versions of my original photo to try to somewhat replicate the designs in the actual setting, albeit without showing the extra thickness of the openers (which was beyond my capabilities).

I'd really appreciate opinions on this, as I'm stuck! I'm looking for a clean aesthetic that fits the style of the room, while having the required ventilation (hence the openers). I can't tell which will look better, and I don't want to make an expensive mistake.

It's a 1930s house, and you can see more of the living room pre-redecoration here: https://www.mumsnet.com/talk/property/5161849-how-would-you-do-up-this-living-room

The front of the house looks similar to this (without leaded windows):

@DecorDilemma I just always think that window proportions look best when they are the same as the original. There are some exceptions and sometimes if you are doing a very contemporary renovation you can get away with more simple arrangements.

Problem with UPVC is that the sections are usually very clunky unless you go for the flush casement type rather than the stormproof window design.

Example of flush casement.

If it's a 30s house definitely keep the original window layout, both suggested solutions which remove the central vertical bar make the windows out of proportion with the doors and out of keeping with the property.

It just means the seals are inside the frames and not in the opening/ closing bit resting on the outer frames. They are designed to be waterproof, just the same!
Personally I think they look much classier and since we found out about them I notice every house that does not have them. They are much more symmetrical on the opening/ closing bits. Cost us about £50 more per window.

Only took a Quick Look but I like the last one best too.
