I use galvanized hinges. Either two 2 inch ones or two 3 inch ones, depending on the size of the door and weight of the tortoises that will be using it. I countersink the hinge into the framing of the door. See post number 235 above this one.
Oh cool! Thank you!

I like my larger tortoises to live outside full time. My climate permits this year round with a little help. For people who live where it snows all winter, this type of box is still good for warmer weather, getting them out earlier in Spring, and keeping them out a bit later into fall. You'll need something else for the dead of winter. Or you can move South! :)

The top of this box is half a sheet of plywood, insulated and sealed, so 4x4 feet. The inside of the box ends up being around 40x40 inches when its all done. I use an 18x28 inch Kane heat mat on the floor, and a 21" radiant heat panel on the top. Both are controlled by the same thermostat: https://www.lllreptile.com/products/13883-zilla-1000-watt-temperature-controller
I lower the RHP so that it is within 6-8 inches of the tortoises carapace that lives in the box. I like to screw a plastic shoe box to the back of the box to contain all the extra wires and thermostat. Weather strip seals the top where the hinged lid meets it, and I use plastic freezer stripping across the door to hold in heat when the door is open. The door drops down like a drawbridge and makes a ramp fro the tortoise to get in and out easier. I latch the door shut every night and open the door every morning.

In summer our daytime highs are usually right around 100, with night time lows around 65. I unplug the boxes during this time and temps stay between 70 and 90 in them. In Fall, we have warm sunny days usually into December, so I set the thermostat to 80. As soon as the weather turns cold in winter, I bump the thermostat up to 86, so they always have an area to get warmer in on a cold rainy day here. Spring time brings back warmer sunny days, so I lower the box temp back down to 80. This routine works great for any tropical species like Stars, radiata, sulcatas and leopards.

Here is the box during construction. I frame the plywood walls with 2x4s and use 1.5" rigid foam as insulation. Then I seal it with silicone caulking and cover the walls with plywood inside.

Here is all the electrical stuff going into it:

Here I want to show the weather stripping in place, and the drip loop. The drip loop is simply draping the cord down a bit so that when it rains, the water drips down the cord to the ground instead of following the cord downhill right into the box.

This is a great way to house a large leopard or sulcata in a relatively warm climate. We get cold winter nights in the 20s and this box, built and heated this way, keeps them in the 80s. Because my climate is so dry, I usually add a 5 gallon bucket or some tubs of water to generate some ambient humidity inside the box. People in the South East US wouldn't need to do this.

Questions and conversation are welcome! :)

For larger tortoises, multiple tortoises, and a different heating strategy, see this thread:
This is so cool. I'm in the planning stages of building something similar for my sulcata when he/she gets large enough to be outside and out of the closed top indoor enclosure. You mentioned a 5 gallon bucket or tubs of water to generate ambient humidity - being that I live in the very humid midwest, do you imagine I'm also exempt from needing that (other than maybe the winter months when it can get a little dry)?

Electric heat tends to dry things out, so even people in humid areas usually need to do this. Let your hygrometer inside the box be your best guide.

Wow! This is awesome!!! It's exactly what I wanted to make for my guys but I had no idea where to start. I may reach out during construction if that's ok?

Absolutely. I built a 4x8 box for my friends in GA while I was working there a few years back. I'm happy to help.
