1804 – Clandeboye, Bangor, Co. Down

Ballyleidy House was extensively remodelled and extended for 2nd Baron Dufferin, to form a substantial L-shaped building consisting of a 7-bay southern range and 9-bay range to the east. Described by Lewis in 1837 as “a handsome and spacious mansion pleasantly situated in a rich and extensive demesne”. Throughout the late 1840s and 1860s, other designs were produced to change the exterior of the building by William Burn, Benjamin Ferry, and lastly W.H. Lynn for Frederick Temple, 5th Baron Dufferin. Lynn had worked on other projects for Dufferin in his position as Governor-General in Canada in Quebec City.
