Reference:

I do hereby give you notice that I intend to erect six cottages (of brick) for Mr Levy in King William street near Nicholson St and that Blewett & Lanyon of Collingwood are to be the builders of the works to be executed, and that the said work will be begun on the 23rd day of February 1854 at – o'clock in the -. Dated this 22nd day of February 1854, Gabriel Blewett, David Lanyon.

Levy was possibly Henry Levy or a J Levy. David Lanyon was building in Melbourne in the 1850s. In 1858 Lanyon was the subject of an impassioned letter to the editor in The Argus by John Pascoe Fawkner seeking recompense for Lanyon, who had been injured whilst trying to put out a fire in Mr Scott's house ('The Victoria Insurance Companies', The Argus, 15 May 1858, p.7).
