2010s. There are a number of housing developments current being planned and built. Garden City As part of the publication We Must Go On: A Study of Planned Reconstruction and Housing Frederick Oswald Barnett, along with W.O. Burt and Frank Heath, focused on improvement of housing in Australia and Melbourne after World War II. Barnett and Burt played a significant role in the Housing Investigation and Slum Abolition Board and the garden city movement was a central focus proposed to solve the slum problems in Melbourne. Frank Heath was an architect who produced town plans based on garden city principles, and plans for Kalkallo as a garden city are printed in We Must Go On. The book does not detail the motives for these plans, however they were never implemented, and as a result Kalkallo remained a small township. Urban Growth Boundary Melbourne's Urban Growth Boundary was extended to include Kalkallo in 2010. It was designated as part of the Urban Growth Zone in 2012. Urban sprawl is a divisive topic in Melbourne, as it is claimed to ease housing affordability, but can have significant impacts on the environment, as well as social impacts such as isolation due to a lack of transport infrastructure. The Victorian State Government has expanded the Urban Growth Boundary several times since 2002 as a result of the Melbourne 2030 plan (later known as Melbourne@5million). Melbourne 2030 introduced the notion of creating a limit on urban expansion. However, since the implementation of Melbourne 2030, the boundary has been extended, which is contradictory to a key objective. Plan Melbourne, established in May 2014 highlighted the need for the Metropolitan Planning Authority to establish a permanent urban boundary to replace the urban growth boundary, and restrict further expansion. Today Kalkallo, until the 2010s, was a small town servicing the highway trade and surrounding agricultural district. Current community infrastructure includes: Kalkallo Common (a 9.8 ha crown land grassland reserve managed by Hume City Council) Kalkallo Cemetery Kalkallo CFA John Laffan Memorial Reserve (an 8ha reserve containing two ovals) New housing developments As a result of the urban growth boundary expansion, there have been a number of new housing developments established: Merrifield – Merrifield is an 880 hectare $8 Billion mixed-use development located on the corner of Donnybrook Road and the Hume Highway. Merrifield has been planned as an integrated mixed use development with capacity to provide 20,000 new
