Tom is oh so correct. SO sit back, relax and let my fingers do the talking
Okay I would suggest no smaller than a 40 gallon breeder tank, 36"x 18" x18". This is the smallest that an adult can be housed in.
Now you have two choices for lighting, either the florescent tube ( Reptisun 10.0-link:http://www.petmountain.com/product/reptile-fluorescent-bulbs/504983/zoo-med-reptisun-10.0-uvb-bulb.html
This should be within 4-8" of the baby for optimum effect.
Here is what calcium to be offered 5 days a week on salads and insects:

Or you can use on a stand a Mercury Vapor Bulb ( this is the #1 world wide:

This is a great bulb ! It offers both heat and great uvb for your dragons' health.
If you do decide on this instead of a tube, then keep in mind you need a 4 day "burn" in time, just like the German Halides over a reef tank need. Keep away from direct rays both human and reptile during this period. You will want a minimum distance to be 12". If you can arrange to have the fixture ( need one rated for around 250+*F) to be able to raise it up, then that would be fine.
Though if you try it out the first week in an empty enclosure, you can monitor the temps and find that sweet spot in distance.
This is the calcium to use with this Bulb:

This is also to be offered 5 days a week on first insect feeding and on daily salad.
Here is the vitamins to be offered 2 days a week, on first insect and day long salad. Oh don't use in conjunction with the calcium, separate days:

You can use this with either uvb.
Now, you will want to offer the best diet for your baby, so this is an excellent guide( whomever does the shopping might want to print this out in color):

Use only in Green for daily staples, Black is reserved for 1-2 times a week snacks.
Okay we have the viv size, two choices for uvb, and all the supplements as well as diet.
Let's talk about substrate. This is a huge issue with so many. I'll let you do the research and decide ultimately what you feel is best.
All babies under a year old should be on non-particulate substrate. I use tile:
This is textured ceramic tile. It is easy to clean and keep clean, and it will help little nails stay little
Nice and filed down.
You can also use non adhesive shelf liners and reptile carpets. Both will need laundering weekly so I would get at least two similar lengths.
There is also paper towels and butcher paper.
Now we want to offer a nice space for running around, as well as a high place for the youngster to climb on, as well as a basking spot. You can use a piece of Hard wood from the yard, if you debark it and then bake it in the oven @ 250*F for an hour. This will kill bacteria and parasites. Or you can opt for a pet store stick. I have used Mondo wood in the past, makes a lovely presentation, and plenty of scrabbling places !
You can construct a simple basking spot with some tiles that are piled up roughly so there are "steps" up to the top. Just make sure you adhere those well, as dragons are pretty strong animals. I use 100% silicone, and allow a 48 hour cure time. One other indication that the cure is done, when you no longer smell the ammonia odor that silicone has.
Have I overwhelmed you yet ? I hope not. It will take some time to absorb all this information, and I still have some to impart.
Temps are terribly important to the health of your dragon. You will want to get a probe digital thermometer or a temp gun ( for checking automotive engine temps) for accurate readings.
Your basking should be 105-110*F, warm side should be air temp range 85-95*F, and the cool side should be around 75-85*F. If over night temps don't drop below 65*F in your home, there is no need for additional heat at night.
Well there it all is. You have the basic information to get started. If you want to construct a palace as a forever home, then feel free to pm me, as I have pictorial step by step instructions of the first enclosure I built.
Welcome to the Family !
