Railing/post/header design, beadboard ceiling, floor
Good example of 3 season porch with only screens but has look of windows with transoms and railing.
Working transom windows, door/windows look alike
Railing around top adds presence; windows are an interesting alternative to double hung. Finish carpentry around header and "pillars".
6-lite upper window and double hung lower window combination; lower ledge serving as extra seating and storage.
An idea for the skirting is to use siding (plank or shingle style).
Something like this would be nice to the left or right side of the door into the house.
