This Falls Church, Va home was looking for something specific as part of their screened porch addition. They wanted a door that would allow the segue from the kitchen to the screened porch to be the widest open space possible, while also keeping the cold out during the winter months. Enter Design Builders and the Lincoln Folding Patio Door. This 4 panel door slides completely open to give a 12 foot opening. Design Builders added a special beam over the door as part of the framing.
