About 8ft long by 4ft wide by 5ft tall. Fully screened in to keep the cats out. 3 door front, the 2 main doors open outward, and the bottom foot opens downward. Not 100% completed yet, still needs lights and possibly a few other things I can't think of right now. A heat lamp will be hanging from the crossbar at the back of it come winter time. Also plan on putting some lights above the main tall area. Was thinking about planting some grass seed as well. Top is completely covered and has two 4ft x 2ft cages sitting over it which house a red tail and a bearded dragon. There's still a 4x4ft of space which will be used to make a new cage for my burmese python.
