Rowan suggests that the second scheme was Adam’s preferred scheme, with its refined rear façade, which is balanced with a well-proportioned Ionic portico. Turton’s letter to Adam in July 1788 points to the architect’s preference for this scheme, stating:

‘I did not require a House such as your imagination might suggest… The Design done previous to the one fixed upon to be carried into Execution might shew your Genius, where you was not shackled by Expence; but could never have been supported’

This scheme was also to include an elaborate set of domestic offices connected to the west of the house with its basement level court. King compares the design to that of the domestic offices proposed for Newliston House.

SM Adam volume 42/86 creates an elaborate western entrance façade to the office courtyard, which incorporates a clock tower. This is possibly Adam’s attempt to include the clock presented to Turton by George III, which was eventually inserted in the stable block.

King also notes the level of movement employed in the facades of the second scheme, for which Adam’s later works are renowned. King points to the use of narrow recessed end bays, which are also incorporated in Adam’s designs for Captain Simpson.
