Drawing 11 shows a design for the storey-posts in the coach-house. The timber posts are approximately 9½ inches wide. A brick wall is shown as extending from the back of the centre storey-post, thereby dividing the coach-house into two separate bays; this wall has been added in feint pencil to the plan on the verso.

Drawing 12 is a design for the weather vane on top of the stables. Its iron shaft is clad in copper 'that is exposed to the weather' and is connected to the stone clock turret with a nut and screw.

The verso of drawing 11 mistakenly shows the dimensions as in inches.
