Build Your Own Sunroom


I decided to cover the treated 1x4 decking with a tarp, cut to size, which I duck-taped all around the outer edges. Over this I placed green outdoor carpeting, which I got at Walmart in 6' x 8' mats for around $25 each. After taping them at the seams, it gave me a clean, cozy floor that was sealed against drafts blowing up from underneath.  

Another consideration for the comfortable use of the sunroom is heating and ventilation.
