In order to build a deck on your enclosed porch you will need to know how tall you plan on building your porch as well as if there are any city restrictions. I suggest downloading free porch and deck design software as it includes the price of the required materials as well.
Screened in deck plans can be found on some websites online. Here are a few I've found, www.front-porch-ideas-and-more.com/screened-in-porch-plans.html, and at www.front-porch-ideas-and-more.com/build-a-screened-porch.html.
