His brother, William Jupp the elder (1734–1788), architect, born in London, was likewise apprenticed to their father. He was made free of the Carpenters' Company in 1753, and became a warden in 1781. He exhibited country house designs at the Society of Artists in 1763 and 1764, but his principal works were in the City of London. He rebuilt the London tavern, Bishopsgate Street Within (dem. 1876), after a fire in 1765, and was employed in making plans for the Carpenters' Company's Stratford estate (1769), and improvements to their London Wall property (1777 and c.1784). About 1780 he designed the entrance hall and staircase of Carpenters' Hall, London Wall (dem. 1876). He married Mary Webb (c.1745–1809) in 1765; they had five sons and five daughters. He died at his house in St Clement, Eastcheap, London, on 16 November 1788.
William Jupp's son William Jupp the younger (1770–1839), architect, born in the parish of St Nicholas Olave, exploited his family connections, becoming architect and surveyor to four City companies—the Skinners' (altering their hall in Dowgate Hill in 1801–3), the Merchant Taylors' (building almshouses at Lee, Kent, in 1826), the Ironmongers', and the Apothecaries'. He was also district surveyor for several East End districts. In 1821 he designed a house at Great Gains, Upminster, Essex, for the Revd John Clayton. He was master of the Carpenters' Company in 1831. About 1798 he married Matilda (fl. c.1780–1802), who predeceased him, leaving three daughters. He died at Upper Clapton, Middlesex, on 30 April 1839.
