Melbourne Affordable Housing (2020)

The project concerns the construction of affordable housing in Melbourne in Australia. the design choices are aimed at reducing the time and costs of construction and management, to try to tackle the problem of the high cost of housing in the city.

Melbourne Affordable Housing

Project Details

Design choices:
1. Choose areas large enough to allow settlements of a certain density and preferably close to public transport, especially the tram network which is the largest in the world.
2. Reduce land use by increasing settlement density with tall, multi-purpose buildings.
3. Reduce the size of the individual housing units by increasing the common spaces.
4. Bioclimatic and green architecture systems at high altitude to reduce CO2 emissions and compensate for the lack of gardens in the single-family house with green terraces on the various floors.
5. To reduce construction times and costs in dry steel and wood, with the production of blocks, in the workshop complete with finishes and their subsequent transport and assembly on site.

The individual real estate units are smaller than the average of the homes in Melbourne, in fact they range from 50 square meters of two-room apartments to 80 of three-room apartments up to 105 of four-room apartments. In tears there is a possible distribution with also a duplex apartment. The possibility of variation is considerable considering that the construction system does not require binding intermediate supports.

Structure

All the assembly technology except the foundations is dry to reduce waste time and costs. The main structure is in steel with HEB 340 pillars and HEB 260 and HEB 300 beams. Even if the cost of steel is higher than other raw materials used in the construction sector, in total it is possible to have lower costs thanks to a shorter duration of the work and the lightness of the material that can be transported and handled more easily and durability over the years. The structural mesh is very simple around a central core with vertical connections, columns with a distance of 12.34 m x 5.14m are inserted.
Prefabricated wooden modules are inserted on the steel structure whose dimensions do not exceed 2.40m x 12.00m with H 3.10m so that they can be transported easily, in fact they correspond to the dimensions of the cargo containers.
