Huge enclosure build..

[CloudyCat]

Seeking some suggestions on a very large enclosure build. 8 feet long, 6 feet tall, 3 feet deep.
We plan on making the enclosures entirely out of melamine and glass.

Here's the plans:

The 400 gallon marked "Artemis" is for a jungle carpet python, the 130 gallon marked "Apollo" is for a ball python, and the 180 gallon marked "Simone" is for a corn snake.
An ackie monitor will be going in either the other 130 or the 270.
All enclosures must be able to hold humidity without molding. Any suggestions for how to "water proof" the enclosures, or any suggestions in general?

Thank you

You will want to ensure proper ventilation to help resist mold. Build vents low on the cool side and high on the warm sides of the enclosures to allow for convection. The mealmine coating will be quite heavy but should provide protection against water. You could also seal everything using polyurethane or epoxy sealant which should work well.

So, was it ever built? I want to see it if it was.
