Correct me if I'm wrong..

[Mulled Transom on the left] [Not Mulled Transom on the right]

If I'm wrong, you can ignore the rest. :P

I MUCH prefer the look of a mulled transom. To me, unmulled transoms look like office conference room windows. And unmulled transoms make the windows look SHORTER because they add a big horizontal line across the window. Mulled windows make each opening vertical, which tricks the eye into perceiving more height.

My house will have an unmulled transom (windows were already ordered for our semi-custom build when we came onto the scene) and one of the first projects on my list is to replace it with a mulled window, leaded glass window, or stained glass window. Anything but leaving it the way it is.

Mulling the transoms will not add a significant amount of money to the job and I believe they will look much better mulled than frames in a separate opening. The cost of the window treatments, window trim for interior and exterior will far out weigh the cost of the mulling in my opinion.

Thanks for the quick feedback. I loved the look of the mulled windows we had in our previous home. I have realized that I would regret this decision. So a mulling it will be. Now I must sit down and finalize my windows...wish I could find a few grand there.

our builder, whom I adore, tried to do custom mouldings for all of our windows and transoms. It would have created a (roughly) 5" separation between each window and window/transom. Yes, it is a much grander look, but I didn't like how spread out it was. And I wanted to see more of the outside, not more painted wood. We opted back into mulled units and I'm so happy we did. I pinned a bunch of images with wider framing, this one in particular is a decent example of a non-mulled transom.

@mommyto4boys did you end up doing mulled transoms here? Can you share any photos? We are in a similar position of deciding what to do with our transoms over our casement windows for a new build. Thank you!
