I curently have a 8x3x2 cage for my Savannah Monitor sitting in my living room. It is a 8x3x2 galvanized horse trough framed with 2x4s and plywood, with a wood, acrylic, and screen top:

I have the intention of building a top section with glass and wood about 4 more feet. Something like this:

I am moving very soon and my new place is smaller, so I am exploring options for this cage. I am thinking about moving it outside. I live in Southern California and am moving 3 blocks from the Pacific Ocean. I am trying to gauge the measures needed or options for making an this enclosure work outside.
I need to worry about preserving humidity, regulating temperature, limiting bugs in and out, drainage, sealing wood, etc.
Has anyone made this transition? Looking for some insight. For additional info, here is the layout. The grey boxes are the different places I could put the cage.
