Ok, I've come up with a way to make Reptiles, etc... houses.
*needs ES*
Step 1
Lay out your floor. Use any path you like.
Step 2
Lay out your exhibit. Add more flooring if necessary.
I suggest using glass fences for authenticity, and a Dino Danger fence section for a gate.
Step 3
Delete the flooring in the exhibit. Add the biome of the animal you plan to put in it.
Add any small attractions (benches, lights, kiosks) to the concreted section.
Step 4
Place a high, solid fence around the area. Make exceptions for special objects. (fog machines, statues, etc) If you have the zoo wall fence download, use it. Otherwise, use any solid fence.
Step 5
Select an elevated path. Cover the entire exhibit with the lowest possible elevated path.
Step 6
Add your animals to the exhibit. Add trees, (if possible) shrubbery, rocks, and different terrain.
Step 7
Make a two-space barrier around the whole building. Color the terrain whatever you want the building's walls to be.
Step 8
Use the elevation tool to increase the altititude of the ground within the two walls.
Even it out. Delete the surrounding fences.
Step 9
Explore your new building!
