The glass roof is not a bad idea. It would be very French to do that. Like the I. M. Pei pyramid at the Louvre. If it's done, it will be done competently. So many people are watching.

Please, no. I am sick and tired of this international-style glass and steel business. We have plenty of buildings painted from this rather dismal palette. I'd like to see Notre Dame restored using traditional materials.

Right. If you want something modern, build a new cathedral.

Wouldn't that drastically increase the sun exposure on the internal elements and artifacts in the church? Sun damage is noticeable in just a few years, let alone on a time scale of centuries...

The burnt space is essentially Notre Dame's attic. There's solid stone between that space and all the artifacts.

To what end? The roof is on the outside put the inside is vaulted stone.

The glass would only be visible from the outside... unless one wants to get rid of the internal vaults?

The idea would be to turn what was previously the "attic" of the church into a public, park-like space.

That would simply create a gigantic greenhouse that would require enormous energy inputs to keep it habitable during most of the year. Not the most eco-friendly solution.

There are films that can be applied to glass that block infrared light, which would reduce thermal heating.

There's certainly precedent.

It would be on the small side for greenhouses. It could also very well be unheated in the winter, it's just Paris and not Vladivostok.
