[3] Hafodunos is the only example of Scott's country house style in Wales and was the second domestic structure that was built by him, the first being Kelham Hall in Nottinghamshire.

Major-General Arthur Edmund Sandbach CB DSO (1859–1928), a British Army general officer was born at the Hall.

The residential home was shut down in 1993 and the unused building then fell victim to dry rot which had spread rapidly through the servant's quarters into the main house.

In 1998 Conwy County Council were contemplating serving an Urgent Works Notice but the owner had died and left the estate in debt.

[citation needed] On the night of 13 October 2004, Hafodunos Hall was the subject of a devastating fire which gutted the main block of the house, although the conservatories and service wing were virtually untouched.

Those remaining sculptures from the house were removed in 2005[citation needed] and the property was put up for sale in April 2008 with a guide price of £500,000 – £750,000.

[9] The materials used to build the house are a soft red brick with a diaper, flushwork design and extensive stone dressings to windows and doors.

The most notable features are a series of plaster bas-reliefs designed by John Gibson, an international sculptor from Conwy who trained in Rome, and Bertel Thorvaldsen.
