Many of Gibbs’s original drawings are preserved in the Radcliffe Library at Oxford, some of these being included in his “Book of Architecture.” Two of them are reproduced here, one (Fig. 164) is plate 57 of his book, the other (Fig. 165) has not been published. The first is an example of a house with a forecourt and wings connected by open corridors to the central block; in the left-hand wing are the kitchens, in the right the stables. The house is entered through a large hall beyond which is a gallery, with small rooms at each end. To the left of the hall is presumably the dining-room, as it lies nearest to the kitchens, to the right is a room of the same size. There are two large staircases resembling each other in all respects, that on the left being probably the back stairs. Grouped on each side of the staircases are small rooms over which might have been the “intersoles,” although Gibbs does not expressly mention them. In this instance the hall was but one story in height with a room over it, and there were three rooms over the gallery. The same disposition obtained on the top floor, which may have been devoted to guest chambers, as it would appear that the servants were lodged in the kitchen wing, judging by the size of the staircase.

PART OF THE PAINTED DECORATION OF THE WALL OF THE STAIRCASE.] The other and unpublished design (Fig. 165) is of a somewhat different type. The centre of the house is occupied by a vast and lofty staircase mainly lighted from a cupola. Round this is a broad corridor giving access to the various rooms, which are of fine dimensions. The same disposition appears to apply to all three floors, save that on the topmost the corridor is omitted, and thus an open space is provided which gives light to the hall on one side and to a passage on the other, which is taken off the width of the rooms. There is no indication where the kitchens lie; the section shows no basement, and there are no indications of separate wings.
