3 Season Deck

This customer approached me with only a vision in their mind about adding an entertainment area to the back of his house.  They gave me a list of the things they wanted incorporated into the addition and I put them into plan.  The customer wanted to be able to enjoy the summer nights outside without being bothered by the bugs.
