澳洲新房现状：建房周期不断延长，建筑成本居高不下

Core Insights - The analysis reveals that approximately 30,000 approved housing units in Australia have not yet commenced construction, while the construction cycle continues to extend and building costs remain high [1][2]. Group 1: Current Housing Market Status - As of Q1 this year, there are 219,000 housing units under construction, comparable to the peak construction period of the 2010s, but the time required for completion has increased significantly [2]. - The average completion time for new apartments has risen from about 6 quarters a decade ago to over 9 quarters now [2]. - The federal government aims to build 1.2 million new homes within five years, with the closest achievement being just over 1 million homes completed in the five years ending December 2019 [2]. Group 2: Housing Ownership and Quality Concerns - Despite an increase in housing supply, home ownership rates have declined from 67.2% in June 2014 to 66.2% in June 2020, with some newly built apartments having serious defects [6]. - The focus should not only be on supply but also on improving home ownership rates and living standards [6]. Group 3: Recommendations for Improvement - The government should prioritize advancing existing projects to enhance productivity, reduce costs, and maintain quality, rather than merely increasing approvals for new housing [6][8]. - Suggestions include focusing on modular construction and facilitating the movement of construction workers across states and countries [8]. - Addressing housing demand through measures such as reducing negative gearing and capital gains tax benefits, implementing land taxes, or including family homes in pension asset tests could also be beneficial [8]. Group 4: Economic Viability and Planning - The housing supply progress is hindered by economic unfeasibility, particularly in Sydney and Melbourne, where high costs and low property prices slow down industry growth [8]. - Improving zoning regulations is essential to enhance the economic viability of building more housing, particularly apartments [8]. - Increasing housing supply is expected to stabilize prices rather than lead to a significant drop in prices, with the goal being to make housing more affordable [9].
