Original Sirius Building

The original Sirius public housing apartment building in Sydney is named after HMS Sirius, the flagship of the First Fleet. The First Fleet arrived in Sydney from England in 1788 with around 780 convicts aboard to establish a penal colony.
The building was designed and built in 1978-79 to re-house displaced public tenants after a controversial development of The Rocks during the 1960s and 70s. It was notable for being the only high-rise development in The Rocks.
From 2015, the Sirius building was at the centre of another controversy over plans to remove the public housing residents, sell off the building and possibly redevelop the site, with opponents of the plans seeking to secure its protection as a heritage building. Following the NSW Government's decision to refuse the heritage listing in 2017, against the advice of the Heritage Council of New South Wales, the building was put up for sale. Eventually, it sold for $AU150 million. The proceeds of the sale were expected to provide social housing for 630 people.

The purchaser has now refurbished the building to what you see today. On release $AU435 million worth of apartments were sold in one weekend at a rate of $AU118,000 per square metre.

Bound

A major public art piece has been placed outside the Sirius building facing Cumberland St. This six-metre cast bronze sculpture, called Bound, depicting a sea vessel, is made of 85 pieces of luggage tied by 150 metres of rope. Created by Isabel and Alfredo Aquilizan, the artists believe, “The work encourages viewers to reflect on their own heritage and sense of belonging to place, whilst acting as a reminder of journeys taken and explorations still to come. The physical binding of the luggage conveys the act of becoming emotionally and metaphorically bound together through community.”
Now take a wander down the walkway to the right of the entrance to the Sirius building. Here you will discover artefacts unearthed by archaeologists in 2022. Take your time to read the information here and observe the artefacts on display. It’s an amazing glimpse into the past history of this part of The Rocks.
