Just days after a devastating fire consumed Notre Dame Cathedral’s roof and central spire, a heated debate has broken out over whether the 13th-century Gothic landmark should be restored or modernized. Firmly in the latter camp is Studio NAB —the Paris–based design practice has proposed topping the 856-year-old cathedral with a giant educational greenhouse.

In a bid to modernize the Notre Dame Cathedral while staying respectful of the French Gothic architecture, Studio NAB has modeled the greenhouse and apiary after the original roofline and spire.

Envisioned as a beacon for education, solidarity, and biodiversity, this conceptual glass-walled addition follows the original silhouette of the collapsed roofline and central spire, yet provides new programming that the firm believes is more relevant to today's society.

According to ArchDaily, the firm says the design is meant to be "anchored in its time, turned towards the future, and representing the stakes of our time." Titled "Green For All of Us," the scheme calls for a multipurpose space where the community can learn about sustainable urban agriculture and beekeeping.
