Following the establishment of a Royal Navy Dockyard in what would later be known as Devonport, in 1690, these victualling premises expanded substantially. A new Victualling Office was opened in Lambhay in 1707, overseen by an Agent Victualler. From 1729, brewing took place across the Hamoaze at Southdown, where a cooperage was also established; it was capable of producing up to 80 tuns of beer per week and had its own wharf (again, only accessible at high-tide). In 1745, the Lambhay site was further expanded, with the construction of two bakehouses, a slaughterhouse and several storehouses, as well as a new wharf. (The slaughterhouse was later removed to Devil's Point.) The bakeries were capable of producing 50 tons of bread each week, however, the mills which produced the flour were three-quarters of a mile away, making baking a difficult process; nevertheless, these facilities continued in use until 1831. These mills were leased by the Victualling Commissioners from the Town Corporation. The Victualling Office depended on local farmers for fresh produce to supplement the dry goods it provided; inevitably, the local economy could be significantly affected by the varying needs of the fleet.
