Outside, the sun porch/ screened porch got it's screens installed into the framed openings. I designed it to be finished from the exterior, but to save money, the interior of the porch has been left unfinished for now. Finishing the interior will be a future task for my FIL and DH to work on together someday once we are neighbors.
This is what I'd call an "outdoor room".
(click here to read on my website about The Outdoor Connection) The room can be accessed from french doors in the living room, or from the back porch. It is open on three sides, making one really feel as if one is outside when in the space (as opposed to a screened porch that is only open on one or two sides feeling more enclosed). To state the obvious, a screened porch gives one more protection from the elements, and can be used more of the time than a simple deck or patio. (rain, buggy evenings...) This screened porch extends its use even more, by switching into a sun porch during colder months.
It faces south and west, looking toward the back yard and the Catskill Mountain View. With the "Combination Door" inserts we used, the screened panels can easily be swapped for glass panels with the turn of a few screws. Once glass is inserted, this space actually has the ability to gain heat from the sun, both for the sun room, and, when the french doors are opened, for the house as well. During the warm weather months, the roof of the screened porch actually helps keep the house cooler, by shading the western-facing living room glass doors.
So, for summer, a shady, insect-free, breezy respite. For early spring and late fall, a space to catch the diminished sun after/before a cold winter. And for sustainability, the ability to actually help heat and cool the house. That's a hard-working space!
