Drawings 156 and 157 are designs for the stables. They are both in Soane's hand and probably date to around 1801, as they correspond to other designs for the outbuildings from this period.

Drawing 156 shows variant elevations, the two middle ones showing a long, low structure punctured but sets of three niches at the outer edges. The lower one shows a central colonnaded entrance within an arch, the upper one a series of three tall central arches. The third elevation above these probably shows the rear of the building and two plans indicate the symmetrical internal arrangement of sleeping quarters and stalls.

Drawing 157 shows a similar elevation, with more ornament. The central arch is framed by two pilasters on either side with arches and roundels between each pair. The plan suggests that Soane intended to use as much of the previous structure as possible (marking the present stable), perhaps merely adding a facade.
