One of the first houses mentioned in the newspapers was an elegant Villa built under Verge's superintendence for George Allen, solicitor at his estate Toxteth Park at Glebe near Sydney. It was nearby Hereford House, George Williams' elegant mansion which was also built by Verge. 
Elegant villas on Woolloomoolloo Hill were built under his orders said to by worthy of the suburbs of London in appearance.
In 1832 Verge began a shop and premises for Samuel Lyons at the corner of George street and Charlotte place said to be spacious and of elegant design.  The construction under the superintendence of Mr. Clarke was not without difficulties however as can be seen in the court case detailed in the Sydney Monitor
He designed among many other buildings, - Barham at Pott's Point Sydney, Tempe House for A.B. Sparke, Lyndhurst at Glebe for James Bowman and the 'Paterson Arms' near Paterson (builder Ralph Mills Clarke).

Mr. John Verge, of Austral Eden, on this river, expired at his residence on the evening of the 9th instant. An attack of apoplexy which came on gradually, first causing giddiness and partial paralysis, then loss of speech, and finally death, all of which occurred in so short a space of time, that ere the messenger sent to procure medical assistance reached Kempsey, Mr. Verge had ceased to exist. The deceased gentleman passed out of life so easily, that he appeared rather to have fallen into a quiet slumber. For many years Mr. Verge was known in Sydney as Colonial Architect and came to reside amongst us about twenty years, since. He has left behind him a very extensive and valuable landed property, extending for a considerable distance along each side of the river, and occupied by a a numerous tenantry' - Mr. Verge it is understood, was 86 years of age, at the time of his death.
