The door feels modern and I feel the glass doesn't really have a big effect either way. Since you don’t need privacy and clear glass will let in more light, I’d replace if budget allowed.

There is nothing dated about it but it doesn’t seem to make sense in this situation.

It looks fine but do you want a solid core for insulation/warmth?

The door reminds me of european doors from the 80's. Is it actually dated? Maybe not, but it's what I remember seeing, so my refrence goes there. At the same time, I am not sure a clear glass would be improvement. It's not like the glass shows into some amazing view. Personally I'd do a solid door. there.

No, it is not dated and yes, I would swap out the wavy glass for clear glass...unless you opt for a door with better insulation.

I'm assuming that the breezeway will be prettied up with blooming plants & foliage when the weather allows and maybe holiday lights, etc. during the winter so 'the view' will be nice to glimpse from inside.

It doesn't look dated. I, however, would like a clear glass door especially if privacy is not an issue. Nice to see outside. If you ordered clear glass, I'd make them install clear glass.
