Like all the proceeding schemes for the house, this design was not executed, and comprises an interesting mixture of castle-style and classical elements. According to Rowan, the plan of Dalquharran derives from this design.

The pencil annotations show that this design comprised the fourth scheme. It is listed here as the sixth scheme as it appears to comprise the sixth scheme among the extant drawings, but the annotation suggests that it was the fourth scheme which was drawn out in finished drawings and presented to Lord Derby. Indeed, the intervening schemes – here listed as second and fourth – were presumably never presented to Lord Derby, or developed beyond the early design phase.
