Can this porch be built with the idea that the screened sections can be added easily at a later date? In other words, we want an open porch with columns but want the option to be able to change it to a screened-in porch without major reconstruction? »
George Alford As a contractor I can tell you it is possible without any complications at all. Have your contractor to have a screen contractor to come out during the build to consult with him or her. Dependent on the way the columns are built the inside jambs can be built at the same time the columns are built and then stored away. When the windows come you will only need to remove the jambs replace them with the jambs that are already precut to fit the screens. This will give you a cleaner look without having to install brackets or 3/4 trim to support the screens. Good luck.
Skylights can add more natural light to this covered space during the day and provide a nice night sky view after dark.
Tip:If possible, keep the flooring consistent from indoors to out. Here, this move connects the screened-in porch to the outdoor patio and eases the transition between the two spaces.
