The property burned down in 1852 and James Graham, 4th Duke of Montrose commissioned the country house of Buchanan Castle as a replacement, which was built in 1852-1858 and stands 0.5 miles (0.80 km) to the southeast.

In 1790, William Henry Playfair was commissioned by the James Graham, 3rd Duke of Montrose, to design alterations to the house.

The 4th Duke and his wife raised and trained racehorses on the estate in the 19th century;[6] their daughter, writer Violet, Lady Greville, was said to have enjoyed an ideal childhood here.

[7] Buchanan Auld House was destroyed in a fire in 1852, and William Burn was commissioned by the 4th Duke to replace it.

[6] Burn designed an extravagant manor in the Scottish baronial style, enclosing an L-plan tower in a clutch of turrets, bartizans and stepped gables.
