The Jolimont Railway Yards that occupied the southern edge of the Hoddle grid were considered for redevelopment many times throughout the early to mid 20th century. In 1963 Victorian premier Henry Bolte announced that the State Government was to sell the air-rights over a small portion of the railyards closest to Flinders Street, up to Swanston Street, which was occupied by the Princes Bridge railway station. The £5 million project would feature two 15 storey office blocks along with a public plaza, and a new entrance to the station. The new development would become the ‘gateway’ to the city, and was to be known as Princes Gate. Leslie Perrot and Partners were chosen as project architects and the development was funded by Princes Gate Pty Ltd, jointly owned by Lend Lease and Oddenino's Property and Investment Co of London. Construction was completed in 1967. The Victorian Employees Federation leased 12 floors in the East tower, while the Gas and Fuel Corporation leased 10 floors in the West tower. The buildings housed a total of of office space, split level parking for 186 cars along with of retail spaceon the ground level.
Architecture
The towers were designed in the postwar corporate International Style, by Leslie M Perrott & Associates. The lead architect on the project was David Simpson, developing the complex design for a large three storey podium containing car parking, with retail spaces that faced onto Flinders Street, and a new access to the station platforms. The development also featured a raised public plaza that occupied the important Flinders/Swanston intersection corner, designed to allow an open vista to St Paul's Cathedral and also function as a public square that was raised up from the noise and traffic of the streets below, which Simpson later felt was not the most successful part of the design. The towers were 17 storeys high and reached in height. The towers featured vertical strips of aluminium framed windows and were constructed with brown bricks from the East Burwood brickworks. The office floors were punctuated by a regular grid of structural columns spaced apart. The ground floor retail spaces development housed a supermarket, ANZ bank, clothing stores, laundromat and the notable music store, Central Station Records. The buildings were built over the still functioning Princes Bridge station, the terminus of the Epping and Hurstbridge lines since 1910. The stations separate identity and name was lost when it was merged into Flinders Street station in 1980, and integrated as platforms 14, 15 and 16.
Public reception
The towers elicited mixed reactions from the general public when first unveiled. The towers were appreciated by some as modernist architectural icons. However, many Melbourne residents regarded the towers as eyesores and criticised their size and placement. The towers were considered to have cut the city off from the river and also detracted from St Paul's Cathedral and the heritage facades along Flinders Street. The towers were much larger than any of the surrounding buildings and were said to have dominated the surrounding context. An Australian Women's Weekly article from 1969 expresses the general public sentiment towards the towers at the time:
Demolition
Following the subdivision and privatisation of the Gas and Fuel Corporation in 1995, Premier Jeff Kennett announced in 1996 that the Princes Gate towers were to be demolished for a new arts complex and civic hub. By this time, they were generally seen to be an eyesore, and their demolition was welcomed. The towers were demolished floor by floor in 1996/97, and what became known as Federation Square was built 1997-2002.
