Room with window looking onto high dry stone wall

[Finnyhaddock]

We are toying with this idea. There would be a glass roof dome and an opening into a long dining room with French windows at the far end.
This is so we could create a kitchen/dining room.
I'm just concerned about this new room - which would be a lounge- feeling like a box.
Any thoughts?

how high is the wall? can you grow a plant up the wall? how close is the window of the house to the wall?

Window film or a stained window? How big is the sill? Can you cover it with plants? Or do you own the wall outside and can plant climbers?

The wall is about 5 foot and we own it. I did think of stained glass. It is a beautiful wall (part of a churchyard) but because it would mean extending the current room into some spare land it would take the window closer.
Hope that makes sense.
We could, of course, keep things as they are but it would mean foregoing the idea of a kitchen with dining room alongside.

The wall could be a fantastic feature through the window...lit by up and downlighters.

Maybe feature mirrors in the room to reflect the light as well?

Thank you for all the ideas. The mirror one is good.
I just don't want it to look or feel like a cell. X

It won't be like a cell, you just need to balance the lovely features. Jealous of the glass dome ceiling, that will make the room very bright. What is the window frame like, is it old and lovely or PVC? If PVC I'd spend some money replacing it making it beautiful however you decide to dress it.
