Tired of using wood and TONS of sealant!!! Need ideas for new enclosure.

Im housing a group of timor monitors.
approx demensions will be; 5-6' tall x 4' wide x 3' deep

There is going to be 1' of soil, and constant moisture(a little water accumulating) beneath the substrate.

The enclosure needs to be visually appealing, as it will be displayed in my living room.

Thanks for any ideas, they are very much appreciated!

Best regards,
Michelle
