King notes that on execution the scheme for the exterior was somewhat simplified. The Corinthian pilasters intended for the façade were replaced with an Ionic order and the proposed rustication for the ground storey is omitted. The design for the south front includes a more elaborate string course, but on execution the more modest string course designed for the western façade was applied to the whole scheme. The fanlight which Adam designed for the front door survives, and as King notes, it is an exquisite piece.
