This final scheme for additions to the house makes use of shallower pavilions on the west front than the previous schemes (Adam volumes 21/56 21/57, 21/209, 39/86, 39/93-99). This leaves space for additional wings of domestic offices arranged around courtyards to be attached to the east front of the central block by long link walls.

In this scheme the half-sunk basement, and bedchamber storeys only extend under and over the central block and the two smaller western pavilions, but not the domestic courts to the east.

We can see from the plan of the principal floor (Adam volume 39/90) that Adam was also proposing a rearrangement of the interior of the central block, giving it differently shaped rooms. One example of this is the great dining room, which is similar to that executed at Harewood House, with a large apse in one wall.
