the cornice assembly may also include a gutter 20 in which case the facia 12 forms the back side of the gutter 20 a significant advantage may be gained through a unitary constriction formed as one piece of the cornice assembly 10 in terms of the amount of labor needed to install the cornice assembly 10 with a unitary construction effort need only be spent on attaching the cornice assembly 10 to the building structure while effort spent on fabricating the cornice assembly 10 is completely eliminated the cornice assembly 10 may be used in with walls made of any suitable outer sheathing building material known in the art such as plywood fiber board celotex osb oriented strand board and the like in a second embodiment as best seen in fig2 the cornice assembly 22 may be made of two or more trim members which are connected together to form the overall cornice assembly 22 for example one trim member may comprise the gutter 20 the facia 12 and the soffit 14 while another trim member includes the crown 16 and the frieze 18 in this embodiment the trim members are preferably constructed such that they may be press fit together however any suitable means of connecting the trim members to form the cornice assembly.
