His son, Matthew (1725–1803), was responsible for the Neo-Classical work at Charlton House, Wilts. (1772–6). Robert William Furze Brettingham (c.1750–1820), grandson of the older Matthew Brettingham, designed several gaols, including the noble front to Downpatrick Gaol, Co. Down (1789–96), and was responsible (with S. Woolley) for the charming Gothick choir refurbishment in the Cathedral of the Holy and Undivided Trinity, Downpatrick (1795). For Arthur, 2nd Marquis of Downshire (1753–1801) he carried out enlargements of Hillsborough House, Co. Down (c.1795–7), drawings for which were exhibited at the Royal Academy in 1797. George Smith was trained in his office.
