Most of us have already posted our enclosures. Have you done any looking through the section that interests you? You'll find sulcata enclosures in the sulcata section, etc. And if you look in the enclosure section, besides the questions, there are a lot of pictures posted there too.
Why don't you tell us what kind of tortoise you have, and maybe we can help you find the pictures for that type.
I see you have a Russian. You can check out the new enclosure I'm building, but it is for 2 Leopard Hatchlings but would house a Russian for most all his life (it's 4X5) if you remove the center wall.
Of course, you'll have to wait and see how it finishes up before you try to emmulate it...and that wont happen for a couple or more weeks
here is what my table looks like at the moment, some are from the construction stage. but ive got a Pair of RT in a 3x5 table. they started in 55gal rubbermaid tubs
