Northwood (NSW), NSW
By Lauren McCaleb · Reviewed by Dylan Duncan ·
Northwood is a quiet, leafy residential suburb on the Lower North Shore of Sydney, occupying a small peninsula on the northern bank of the Lane Cove River between Woodford Bay and Gore Creek, about eight kilometres north-west of the city centre in the Municipality of Lane Cove. The suburb takes its name from Northwood House, a gracious residence designed by the noted colonial architect Edmund Blacket and built for Jane Davy in 1878; the name was chosen simply as a description of its setting, a wooded rise in the north. Mrs Davy is said to have paid for a ferry of her own so that her family could travel to the city by water. Today the house survives as a heritage landmark, and quiet streets, water views and bushland define the suburb.
