          Wood door may be classified as:
-      Paneled doors
-      Flush doors
PANELED DOOR
          Paneled doors are frame with stiles and rails around a panel or panel of wood  or ply wood because the door is hinged on the side to open, it tends to sink on the lock stile.
        The stile and rails have to be joined to resist the tendency of the doors to sink.
FLUSH DOOR  
        A variety of flush doors are manufactured with plain flush faces both sides and fibreboard facing press moulted often with comparatively shallow sinking to resemble the appearance of a paneled door.
1.3    OBJECTIVES OF THE PROJECT
        This project is aimed at using timber towards the construction of the panel door by the carpenters.
        It will try to examine some of the importance of timber to the student while undertaking the project endeavour in using timber in the construction of a pane door.
1.4    SIGNIFICANCE OF THE STUDY
        The essence of this project is to draw the attention of the students, carpenters and individuals in constructing a panel door using timbers.
        This research draws the attention of the individuals to the need of timber for construction of a panel door as well as its uses in storing and making a panel door.
