Cornice return

A cornice (from the Italian cornice meaning "ledge") is generally any horizontal decorative molding that crowns a building or furniture element – the cornice over a door or window, for instance, or the cornice around the top edge of a pedestal or along the top of an interior wall. A simple cornice may be formed just with a crown molding.

The function of the projecting cornice of a building is to throw rainwater free of the building’s walls. In residential building practice, this function is handled by projecting gable ends, roof eaves, and gutters. However, house eaves may also be called "cornices" if they are finished with decorative molding. In this sense, while most cornices are also eaves (in that they overhang the sides of the building), not all eaves are usually considered cornices – eaves are primarily functional and not necessarily decorative, and a cornice has a decorative aspect to it.

The projecting cornice of a building may appear to be heavy and hence in danger of falling, particularly on commercial buildings, but often it may be very light, made of pressed metal.

In Ancient Greek architecture and its successors using the classical orders in the tradition of classical architecture, the cornice is the topmost element of the entablature which consists (from top to bottom) of the cornice, the frieze, and the architrave.

A rake is an architectural term for an eave or cornice which runs along the gable end of the roof of a modern residential structure. It may also be called a sloping cornice, a raking cornice. The trim and rafters at this edge are called rake-, verge-, or barge-board or verge- or barge-rafter. It is a sloped timber on the outside facing edge of a roof running between the ridge and the eave. On a typical house, any gable will have two rakes, one on each sloped side. The rakes are supported by a series of lookouts (sometimes also called strong arms) and may be enclosed with a rake fascia board on the outside facing edge and a rake soffit along the bottom.
