The Blackwattle site at 461-465 Glebe Point Road has had a varied history since 1884, when the Glebe Corporation yard began to use the land for Council works. From then until 1933 the businesses and private houses on this land were listed in Sands Directory at numbers 461, 463, 465 and 467 Glebe Point Road, and occasionally with no street number.

In 1904-1905 the house "Alston" was listed at 465, and "Bayview" was at 467. Sands Directory also includes the Glebe Corporation yard, the Standard Ammonia Company, the University Boat Club and a Fuel Merchant at this address. There was no 465 listed from 1907-1910. The address for "Alston" was now given as no. 461, and at 467 there were the Glebe Corporation Yard, William Caldwell, the Standard Ammonia Co, the boatkeeper Thomas Steele, "Bayview", and the University Boat Club. There was also a Female Mission Home at no. 467, listed at 463 in 1912.

In 1915 the street numbers ended at 463, with only the Glebe Corporation Yard, Plymell Co paint works and Thomas Steele boatshed left. The Steele boatshed had gone by 1917. Thomas Jenkinson was listed at 465 from 1919-1921, along with the Glebe Corporation Yard.

Daniel Hardy & Sons, Coachbuilders and Wheelwrights' suppliers, made their first appearance at 465 Glebe Point Road in 1921, having moved from Pyrmont. They were listed at this address along with the Glebe Corporation until 1929, when the Corporation disappeared from the directories. D. Hardy & Sons, now described as Timber Merchants, remained at this address until 1972 when Parkes Development bought the property. Parkes Development was headed by Sir Paul Strasser, a friend and gambling partner of Bob Askin, the Liberal politician.

In 1976 or 1977 Parkes Development put in an application to demolish the building and construct residential apartments. This application was one in a long line of similar proposals by the company. They were responsible for the demolition of many fine old homes in the area, especially Stewart St, including Llangolan. The Blackwattle site was temporarily reprieved when Parkes Development went bankrupt after the credit squeeze of 1980-81.
