front/side deck

Our home was added onto in the late 90's. For whatever reason, the person added a 2nd front door (double doors plus) with a porch. We would prefer to keep the front door of the original part of the house and add a wrap around deck where the addition front porch is. We would like to convert the 2nd front doors to large sliders or accordian doors that would be access to the new deck. The home is tudor style.
