Orvis folding dog gate console

Hi- I was wondering if anyone had ever seen a wooden dog gate in which the sides fold into itself and hide behind doors to resemble a console. I found this:

which I think I will try to use for my own plans. We have a greyhound, so we may even need to make it slightly bigger than what's shown. I think it's an awesome way to gate your pet without having to decorate around a massive crate. Any suggestions for things to consider and/or actual plans would be great, since I'm not a pro...
