On each side of High Street, 32 huts had been erected, each 25 feet by 12 feet (7.62 by 3.66m) and spaced 100 feet (30.48m) apart. Each hut was of wattle and daub construction with brick chimneys and thatched roofs. They had two rooms, one of which had a brick fireplace, and were designed to hold ten convicts. By March 1791 about 100 such huts had been completed (Kass et al. 1996: p. 24). Town allotments were much larger than usual, measuring 100 feet by 200 feet (30.48 by 60.96m), and convicts were encouraged to cultivate the land around them and to grow their own vegetables. On the hill above the Crescent and facing down the length of High Street, the Governor's cottage was built using convict labour. Captain Watkin Tench described this residence as being '44 feet (13.41m) long by 16 feet (4.88m) wide, for the governor, on a ground floor only, with excellent out houses and appurtenances attached to it' (Tench 1979: pp. 224–5). The extensive garden setting of the building, as well as its prominent position, with a view over the township, gave some status to what was essentially a vernacular cottage. Although the governor's residence was somewhat larger, and had less occupants, it was similar in form to the vernacular cottages built to accommodate the convicts. From Tench's description it would appear that Governor Phillip's House at Rose Hill was largely constructed of materials which could be obtained locally, primarily timber, 'wattles' and clay or mud. The hip roof form was used for the earliest dwellings, with either a thatched, bark or shingle roof and timber rafters. Timber posts formed the structural framework, and a network of 'wattles' woven from Acacia branches was inserted between the posts and the gaps filled with mud. The walls were then plastered with pale coloured clay, which required constant renewal. There are four images of the house in the 1790s. The 1790 watercolour, 'View of Rose Hill, Port Jackson' (artist unknown); two 1793 sketches by the Italian artist Fernando Brambila, the official artist to Alejandro Malaspina's Spanish expedition to the Americas, Micronesia, and New South Wales; and a 1798 engraving by James Heath which was published in David Collins' An Account of the English Colony in NSW (London 1798) (DPWS 1997: p. 17).
