Scoles was born in London on 27 June 1798, the son of Roman Catholic parents Matthew Scoles, a joiner, and Elizabeth Sparling. He was educated at the Roman Catholic school at Baddesley Green and then, in 1812, apprenticed for seven years to his relative, Joseph Ireland, an architect who was extensively employed by John Milner, then the Roman Catholic vicar-apostolic of the Midland District. Ireland built several Roman Catholic churches, one of the earliest of which was at Hinckley, in Nottinghamshire. He was probably advised on the Gothic detailing of these designs by John Carter. Between 1816 and 1819 Scoles was resident at Hassop Hall, Bakewell, and in Leicester, superintending works for Ireland.
Travel
In 1822 Scoles left England in the company of Joseph Bonomi the Younger for further study. He carried out archaeological and architectural research in Rome, Greece, Egypt, and Syria, often in the company of Henry Parke and Frederick Catherwood. In 1829 he published an engraved map of Nubia, showing the area between the first and second cataracts of the Nile, from a survey made in 1824 jointly by him and Parke, and a map of the city of Jerusalem; his plan of the church of the Holy Sepulchre, Jerusalem, with his drawings of the Jewish tombs in the valley of Jehoshaphat, was published by Robert Willis in 1849.
Early secular work
In 1826 he returned home and resumed architectural work. In 1828 he planned and carried out the building of Gloucester Terrace, Regent's Park, for which John Nash supplied the general elevation. Gloucester Villa, at the entrance to the park, was built completely to his design. At around this time he constructed a suspension bridge over the River Bure at Great Yarmouth. It collapsed with fatal results in 1845, due to concealed defects in two suspending rods.
Anglican churches
Scoles designed three Anglican churches: St Mary's Chapel, Southtown, Yarmouth, St Peter's Church, Great Yarmouth, and St George's Church, Edgbaston, for Lord Calthorpe. His only other work for the established church consisted of some small additions and restorations to Burgh Castle and Blundeston churches in Suffolk.
Scoles was elected a fellow of the Royal Institute of British Architects in 1835, was honorary secretary from May 1846 to May 1856, and vice-president in 1857–1858. Most of his contributions to the society's Proceedings were about the monuments of Egypt and the Holy Land, studied during his early travels.
Family
He died on 29 December 1863 at his home, Crofton Lodge, Hammersmith. He was survived by four sons and eight daughters from his marriage to Harriet Cory of Great Yarmouth, whom he had married in 1831. The eldest was Ignatius Scoles who followed his father as an architect, then joined the Jesuits and designed Georgetown City Hall and St Wilfrid's Church, Preston. His third son was Alexander Joseph Cory Scoles who became a Roman Catholic priest and canon and followed his brother and father in becoming an architect. He designed many lancet style Gothic Revival churches in the south of England.
