In an open cornice design, which part is typically exposed to view?

In an open cornice design, the rafters are typically exposed to view, which distinguishes this architectural style. The visibility of the rafters creates a more rustic and traditional aesthetic, showcasing the structure's framework and material. This design choice highlights the craftsmanship and construction techniques used, often enhancing the overall aesthetic appeal of the building.

In contrast, other components of the cornice, such as the fascia and soffit, are usually not fully exposed. The fascia serves as a horizontal board that caps the ends of the rafters and is often covered or finished for aesthetic purposes. The soffit is located beneath the overhang and helps to enclose the eaves while providing a finished look, but it too is not typically part of the open design concept. Trim molding, while decorative, is also generally designed to complement rather than to expose structural elements. Thus, the exposure of the rafters in an open cornice emphasizes the design's intention to reveal the framework rather than conceal it.
