Already a nice size deck....for baking in the afternoon sun and getting eaten by mosquitoes!  An uncovered deck in the central Virginia summer can often be more of a curse than a blessing.   A screened room, however, extends the usability of such a space from maybe three months to upwards of nine or even ten.  Often overlooked when contemplating screened spaces is the need for a convenient place for outdoor grilling.  That must also be addressed.
