- Converted into a cathedral: as, a cathedralized church.
Sorry, no etymologies found.
Perhaps for the dead-enders who added the cathedralized acoustics of their foot traffic to the wondrous mix of sound and image, the images themselves maybe gave the aura of a gratuitously explicit show and tell of a disturbed child's film footage hunt through archives the world over.
It's also supremely energy efficient, with cathedralized insulation in the attic, which reduces energy losses from the ductwork running through what would normally be unairconditioned attic space, and localized "demand water heaters," that provide instantaneous hot water so homeowners don't waste water by letting the faucets run.
