The stepped shelf sits on an egg and dart moulding above a frieze of classical urns, patera and scrolls and leaf decoration. The white statuary carved decoration is applied onto a Spanish Brocatelle background. The terminal blockings have inlaid Spanish brocatelle flutes either side of a carved flute of connecting bells. The ingrounds are carved paterae at each corner with connecting bells running down the uprights and across the header. The jambs are carved with scrolled uprights with a paterae in the centre and a background of Spanish Brocatelle.

This very fine chimney piece has many characteristics of the work of Robert Adam in its design and execution. The jambs are taken from a design from the Palladio which Adam used on several other commissions and the frieze is typical of his elegant Neo Classical design that made him so well respected.
