>>I would like to build the cage about 10' long, 3' high, 5' wide.
If you want to use wood to save money, remember that it typically comes in 4' x 8' sheets. To build a 5' x 10' cage requires large clamps to bisquit-join panels together or to make a series of large frames.
Both are not the easiest tasks for the beginner.
Some plastic sheets come in 5' x 10'. Polypropylene is what I'd look for, but it's not cheap.
If you have some idea of the locality of Reticulated you are getting it might be that a 4' x 8' cage will be sufficient. It certainly will be cheaper. I don't have the specific taxonomic experience to offer advice on this.
>>I want to build a 2' area under the cage to store stuff and incorporate a large tub style drop in pond. Judging the size of this, it will be impossible to move, so i would like to make it so i can take it part and reassemble as needed.
Good idea and not too much more difficult.
>>As for the vewing area(front) I want to go with a sliding type door, i am considering a window from menards, simply beacause its easy to frame in leak proof, and lockable.
I have heard of problems when using these windows. I believe the slight flexibility that every cage has makes them not function properly.
Follow the link below for more advice. I really don't know the best way to make a sliding door for something as strong as a Reticulated Python. But people do use them so you should be able to find more information.
