Governor that he will be pleased to grant an allowance for candles used in writing the Public accounts done after office hours, as it is impossible to get the same performed during the day without neglecting other duties... With the arrival of 300 convicts and ticket of leave persons, Perth had the labour necessary to commence building many substantial projects. The first of these that Jewell worked on were the Claisebrook Abattoirs, of which only drawings survive, and the Colonial School on St Georges Terrace that now houses the National Trust. The Colonial School was built in two stages, the first being completed in 1854 and two wings being added in 1868 giving it a rough crucifix form. To provide for the convicts, Jewell designed the Perth Gaol in 1854. All of these building utilised limestone carted by barges from quarries at Rocky Bay. In about November 1854, he also designed Holy Trinity Church, York, which is in brick and of Victorian Romanesque design, and is still standing. The Cloisters With the colony lacking in funds Jewell also turned to brick construction in Perth. James Brittain had already established a brick yard in East Perth, supplying a wide range of wood fired bricks. The first major brick project by Jewell in Perth was Bishop Hale's Collegiate School of 1858. This building was designed based on a pattern already established with King's School in Parramatta, New South Wales and St Peters College in Adelaide, South Australia. Bishop Blagdon Hale paid for the building of the school out of his own purse, requesting an English-Gothic design. The building became known as The Cloisters due to the effect of the ground floor verandahs. The Cloisters uses a patterned brick style set in Flemish bond with diaper patterns to selected panels. The building was first classified by the National Trust in 1973, and together with the adjoining Port Jackson Fig Tree was placed on the permanent heritage register on 20 October 1995. The Cloisters is the oldest building designed by Jewell in Perth still standing at its original location. With the building of the Hammersley Iron offices in the early 1980s behind The Cloisters the area is now known as Cloisters Square. Government House Government house was designed by Officers of the Royal Engineers and James Manning with building commencing 1859. The Convict Establishment was based in Fremantle, so Jewell was appointed to supervise
