The existence of a rough pencil-drawn desk and bookcase on one of the window piers in the book room wall elevation (Adam volume 50/53) suggests that this finished drawing for a similar arrangement comprises an alternative for furnishing that room.

Regarding the design of this piece of furniture, Harris has noted, 'Although the bookcase is entirely English in form and detail, it has something of a French flavour owing perhaps to its gold and white colour and slender proportions.'

None of Adam's designs for Colebrooke are known to have been completed owing to his financial difficulties. See scheme notes.
