Gogerddan Mansion was built in the late seventeenth to early eighteenth century, and much extended in 1860. The estate was owned by the Pryse family from at least the fifteenth century: the family was descended from Gwaethfod, Lord of Cardigan in the eleventh century. Gogerddan was the principal estate of the county, wealthy from lead-mining from the seventeenth century. The estate was sold by Sir Pryse Loveden Saunders-Pryse in 1949 to the University College of Wales. Since that time the interior has been largely modernised. The facade, however, has been preserved, of painted stucco topped by slate roofs and red and yellow brick chimneys with cornices.

The oldest datable feature of this building is the main staircase, dating from the mid eighteenth century. However there exists archaeological evidence indicating that there was an important medieval and fifteenth century house on site, including a richly carved beam which has since been moved to St. Fagan's Museum, and a number of reused timbers throughout the property.
