First thing I would do is to check with a carpenter to see if your deck supports are strong enough to support the weight of adding on for a 3 season room. Mine were not so we had to add more support. We attached a roof onto the house and went from there to close things in.
Any changes to structure require submitting plans to local Building Code Office for approval and permit. That's the first place to begin. The size of the deck determines generally what codes you need to follow.
What are the specs of this deck? How is it attached to structure? Joists? Beams? Support posts? What type of wood? Termites? How long do you expect this addition to last if supported by existing support system? Other? What do codes require? You need to do your homework.
Do you want to build on the existing deck? What condition is the deck in? Will the deck support the extra weight?

Lots of legwork to do before building. Good luck!
You'll need to consult a contractor and building codes for your area.
