Australia's Housing Crisis Deepens: A Call for Alternative Construction Methods

Housing affordability and accessibility across Australia are projected to decline, with regional shortages expected to intensify.

Industry experts suggest that adopting alternative home construction methods, such as flat-pack and modular homes, is necessary to address these challenges.

Factors contributing to the situation include rising material costs, labor shortages, supply chain disruptions, and increased demand for housing.

Challenges in the Housing Sector

The national housing sector faces several pressures leading to declining affordability. Rising costs of materials, a shortage of skilled labor, and supply chain disruptions have contributed to higher property prices. Demand for housing has also outpaced available stock, exacerbating the issue.

Nerida Conisbee, chief economist at Ray White Group, noted that housing delivery has become more difficult and expensive, restricting supply and exerting upward pressure on prices. Significant cost increases in 2022 and 2023 were attributed to a lack of skilled tradespeople and elevated material costs. While growth moderated temporarily, it did not return to previous levels, with recent increases primarily driven by labor shortages and capacity constraints within the construction sector. Conisbee also indicated that current global factors, such as the Middle East conflict, leading to higher fuel costs and shipping disruptions, are expected to have an impact.

Regional Shortages Intensify

The Housing Industry of Australia (HIA) has warned that regional housing shortages are expected to intensify due to increasing costs and ongoing workforce shortages. In north-west Western Australia, for example, accessing local trades is challenging, and a lack of available housing deters potential workers.

Tim Fleisher, Executive Director of TIMIK, a local building company, reported sourcing trades from distant locations, such as roof framing teams from Broome (1,000 km away) and roof sheeting teams from Perth. Fleisher also identified accommodation as a significant obstacle, as smaller building firms often cannot afford expensive camp accommodations for staff, leading to project delays.

A report by the HIA indicated that rising land prices are also impeding the construction of new homes. Michael McGowan, Executive Director of HIA Western Australia, explained that these challenges make it risky for builders to commit to new projects in regional WA due to uncertain skilled labor availability. McGowan noted that while the Pilbara housing construction market was "subdued" before COVID-19, post-pandemic demand has outpaced the available workforce. He suggested developing local apprentices as a potential solution.

Dave Penfold, director and co-founder of Shed House Australia, suggested that recent state election housing policies in South Australia did not fully address upcoming challenges. Penfold emphasized the need for policies to incorporate different home-building approaches, noting that the domestic construction industry has predominantly used traditional methods.

Alternative Construction Methods

Alternative housing options, such as flat-pack and modular homes, are being proposed as solutions to alleviate affordability challenges.

Flat-Pack Homes

Shed House Australia offers flat-pack kits for homes designed for quicker and more efficient construction compared to traditional methods. These kits are pre-punched and shipped flat-packed, with owner-building options available. Such homes can reach lockup in four to eight weeks and may cost up to 20 percent less than conventional construction for similar designs. Designs range from $52,000 to $145,000, plus GST, with final costs varying based on location, site conditions, trade availability, and chosen finishes.

Modular Homes

Modular homes are gaining popularity across Australia, particularly in regional areas. These homes are prefabricated in a factory, often complete with bathrooms, kitchens, and internal fittings. The units are then transported to the site and assembled on prepared foundations. This method is considered more cost-effective due to reduced on-site labor requirements.

Examples include:

  • Two modular homes in Kadina, South Australia, built by BoxMod in Chinese factories and shipped for assembly, were sold last year. These homes can arrive within months and be installed within weeks, priced under $300,000, excluding land costs.
  • In Karratha, Western Australia, local entrepreneurs Ian Abbott and Carissa Ives are developing 12 build-to-rent properties using modular housing fabricated in Perth. Project manager Carissa Ives stated that modular housing offered a time and cost-effective approach given the limited availability of local builders, with a four-week turnaround for manufacturing, assembly, and fit-out per house. The 12 homes are projected for completion within eight months.
  • The City of Karratha is also implementing modular solutions through its "Project Dorothy" initiative, which will involve installing three modular apartment complexes in the suburb of Bulgarra. This project is expected to provide over 100 new rental properties later this year.

Nathan Casserly, executive director and co-founder of OC, noted that alternative housing types like flat-pack, modular, and tiny homes could be suitable for regional areas, especially as international travel becomes more expensive and regional building costs increase. He suggested that younger generations might be more receptive to these housing solutions. While building such homes in metropolitan areas might present challenges due to land constraints, apartments could significantly impact city housing.
