The elder Bonomi worked in England for the Adam brothers and Thomas Leverton. His reputation for severely neoclassical country houses, notably Longford Hall, Shropshire (1789–94), and Laverstoke Park, Hampshire (1796–9), is recorded in Jane Austen's Sense and Sensibility. Of Gothic he knew nothing and cared less; but his second surviving son Ignatius, who trained under him, moved to Durham at his father's death, and became a competent designer of both neoclassical houses, such as Egglestone Hall (c.1810–15), and Gothic churches, such as St Oswald, Bellingham (1837–9), for the newly enfranchised Roman Catholic faith. These are less remarkable than his bridges, for which he was surveyor for County Durham: his Skerne railway bridge (1824–5), near Darlington, is the first designed by an architect. J. L. Pearson was his pupil and assistant.
