Moy was purchased from the Campbell of Cawdor family by Major George Grant, in 1733. It was inherited by his nephew, Ludovic Grant (d1790), the second son of Sir Patrick Grant, 4th Baronet (1654-1755). Ludovic succeeded as the 6th Baronet following the death of his older brother Sir Alexander Grant, 5th Baronet, in 1772, and he married Margaret Innes (d1780), daughter of Sir James Innes of Belvery, 5th Baronet.

Ludovic Grant demolished the Campbell house and rebuilt Moy House on the same site in 1752 to designs by Collen Williamson (1727-1802). Williamson's house is composed of a three-storey, five-bay central block, with lower, three-storey wings, arranged in a U-shape. In 1759 Robert Adam made proposals for replacing the central block, but these were rejected in favour of designs by his older brother, John Adam (1721-92), who made internal alterations to the existing central block in 1763-5.

The house passed into the possession of various members of the Grant family, until it was sold in 1922. It was placed on the British Listed Buildings register (category A) in 1971, but was largely gutted by fire in 1995, and remains a ruin.
