We need to change council planning rules that prevent community members from having a say on proposed development in their local area.
Good urban design and walkability boost local economic activity by increasing public activity, but cities need to pay more attention to the effects of microclimates on streets and public spaces.
Planning controls in Melbourne were eased 20 years ago, with mixed results, and new limits are now in place. Will other cities that have eased height limits, like Adelaide, avoid the same mistakes?
Australian cities have a glut of parking, even as politicians move to protect parking spaces or promise even more. There are better ways to keep congestion manageable and our cities liveable.
Traffic impact assessments required of major building developments mainly focus on the movement of cars, but these account for only 30-40% of trips by inner-city apartment dwellers.
New South Wales now has a minister for public spaces, a nod to their importance to the life of a city. But not all is well with public spaces and some issues demand the minister's attention.
The problems with housing systems in Australia and similar countries run deep. Solutions depend on a fundamental rethink of our approach to housing and its central place in our lives and the economy.
Much of the growth in our cities is in the outer suburbs, now home to around 5 million people. And that creates problems like traffic that detract from the advantages residents see in living there.
Tiny houses aren't for everyone, but most people who live in them are positive about the experience. Yet planning laws still make this way of life harder and less secure than it could be.
Planning innovations around the world offer inspiration, but ultimately the innovations needed to make Australia's sprawling cities more sustainable must be shaped by local conditions.
The health concerns that dominate public submissions to the parliamentary inquiry into WestConnex are a reminder that papering over such issues comes back to haunt governments.
There are thousands of empty parking spots in cities. So what can we do to make better use of this space?
Local planning rules have prevailed in a long-running dispute over a proposed Gold Coast quarry that threatened the amenity of nearby residents and koalas.
There is a long, dishonourable history of detrimental policy going back to the 15th century.
The population growth is in the west, but most of the jobs are still in the city centre. Three major development proposals could help reshape Melbourne in ways that help overcome this costly mismatch.
Ruth and Maurie Crow were early advocates of the compact city. They also warned 50 years ago that a clear justice intent was needed to shape cities for their citizens rather than vested interests.
Australian governments are faced with a choice: make the difficult decisions to fix planning systems so more houses can be built, or tap the brakes on Australia's migrant intake.
Residents of established middle suburbs are slowly coming round to the idea, but governments and the property sector lack the capacity to deliver compact cities that are acceptable to the community.
New research has found a marked increase in people, particularly among women over 50, who are building or want to build a tiny house. However, inflexible planning rules often stand in their way.
Traditional urban planning is being stretched by the pace at which renewable energy systems are being installed. New codes and guidelines are needed to manage emerging conflicts over land use.
