The cornice only is carried around the room at the ceiling, and in the staircase hall only the cymatium and corona of the cornice; but over the archway, supported by a colonnade of four fluted round columns, a complete entablature with nicely worked classic detail is employed and given added emphasis by several inches' projection into the reception hall.

The mantel itself took the form of a complete entablature above the fireplace opening, supported by pilasters at each side, the pilasters usually being carried up through the entablature by projections in architrave, frieze and cornice respectively, and the cymatium of the cornice forming the mantel shelf.
