Adam’s overhauling of the interior at Byram included the decoration of the drawing room in his new Etruscan idiom, a style Stillman describes as 'the most striking innovation of the decade'. Adam only produced some eight rooms in the Etruscan style, all during the 1770s and 1780s, of which the dressing room at Osterley is the only one of significance to endure. This scarcity of Etruscan designs gives notability to the Byram drawing room as an unusual occurrence of this major development.

Three drawings relate to Sir John Ramsden’s drawing room, which was situated in the main central part of Byram (Adam volumes 14/83, 23/151 and 50/70). Given that Adam arrived at the furnishing phase, providing a mirror design for the drawing room (Adam volume 23/151), the room was probably executed but did not survive the demolition of 1947.
