This Porch uses a combination of Models SP6004 and SP6006. The SP6006's with the operating gliding windows are used in the end walls to adjust ventilation during the spring and fall seasons. The SP6004's are used in the front wall to maximize the panoramic view. In the summer season all the glass panels can be removed for conversion to a fully screened porch. The 36" high base wall and "hip" style roof was site built by the contractor.
