Wild cities and concrete corridors: How AI is reimagining the landscape
A new AI-driven account by leading landscape architect Jon Hazelwood pushes the boundaries on the role of ‘complex nature’ in the future of our cities

Drifts of ground cover plants and wildflowers along the steps of the Sydney Opera House, traffic obscured by meadow-like planting and kangaroos pausing on city streets.
This is the way our cities could be, as imagined by landscape architect Jon Hazelwood, principal at multi-disciplinary architectural firm Hassell. He has been exploring the possibilities of rewilding urban spaces using AI for his Instagram account, Naturopolis_ai with visually arresting outcomes.
“It took me a few weeks to get interesting results,” he said. “I really like the ephemeral nature of the images — you will never see it again and none of those plants are real.
“The AI engine makes an approximation of a grevillea.”
Hazelwood chose some of the most iconic locations in Australia, including the Sydney Opera House and the Harbour Bridge, as well as international cities such as Paris and London, to demonstrate the impact of untamed green spaces on streetscapes, plazas and public space.
He said he hopes to provoke a conversation about the artificial separation between our cities and the broader environment, exploring ways to break down the barriers and promote biodiversity.
“A lot of the planning (for public spaces) is very limited,” Hazelwood said. “There are 110,000 species of plants in Australia and we probably use about 12 in our (public) planting schemes.
“Often it’s for practical reasons because they’re tough and drought tolerant — but it’s not the whole story.”
Hazelwood pointed to the work of UK landscape architect Prof Nigel Dunnett, who has championed wild garden design in urban spaces. He has drawn interest in recent years for his work transforming the brutalist apartment block at the Barbican in London into a meadow-like environment with diverse plantings of grasses and perennials.
Hazelwood said it is this kind of ‘complex nature’ that is required for cities to thrive into the future, but it can be hard to convince planners and developers of the benefits.
“We have been doing a lot of work on how we get complex nature because complexity of species drives biodiversity,” he said.
“But when we try to propose the space the questions are: how are we going to maintain it? Where is the lawn?
“A lot of our work is demonstrating you can get those things and still provide a complex environment.”
At the moment, Hassell together with the University of Melbourne is trialling options at the Hills Showground Metro Station in Sydney, where the remaining ground level planting has been replaced with more than 100 different species of plants and flowers to encourage diversity without the need for regular maintenance. But more needs to be done, Hazelwood said.
“It needs bottom-up change,” he said. ““There is work being done at government level around nature positive cities, but equally there needs to be changes in the range of plants that nurseries grow, and in the way our city landscapes are maintained and managed.”
And there’s no AI option for that.

As interest rates, inflation and market sentiment fluctuate, investors are being urged to focus on data, not panic.
Australia’s median advertised rent has climbed to a record high, with every capital city recording quarterly price growth despite a slight lift in vacancy rates.

Australia’s rental market has reached a new milestone, with national median advertised rents climbing to a record $670 per week in the June quarter as prices continued to rise across every capital city.
New data from realestate.com.au shows national rents increased 3.1 per cent over the quarter and 6.4 per cent over the past year, while capital city rents rose 2.2 per cent over the quarter to a median of $690 per week, up $10 from the March quarter.
REA Group economist Luc Redman said rental price growth had continued despite a small increase in vacancy rates.
“National median rents reached a new high in the June quarter, with widespread price growth across the capitals,” he said.
“The rent increases occurred despite a small increase in the rental vacancy rate over the same period.”
Melbourne and Perth recorded the strongest quarterly growth among the capitals, with rents increasing 3.5 per cent in each city. On an annual basis, Perth led the nation with rental growth of 10.3 per cent, followed by Hobart at 9.1 per cent and Darwin at 7.7 per cent.
Sydney remained Australia’s most expensive city for renters, with a median advertised rent of $800 per week, while Melbourne and Hobart were the most affordable capital cities at $600 per week.
Regional markets were more subdued, with rents holding steady over the quarter but remaining 5.3 per cent higher than a year ago, suggesting the rapid pace of growth outside the capitals has eased.
Mr Redman said the full impact of the Federal Budget’s changes to investor tax settings was yet to be seen.
“The May Federal Budget, which announced sweeping changes to investor tax settings, occurred in the middle of the quarter, so the full impact on the rental market is yet to be seen,” he said.
“While the vacancy rate has edged higher, the expected decrease in investor demand due to the budget’s tax changes could slow the pace of new supply, putting further pressure on rents.”
The report also found house rents continued to outpace units, rising 2.9 per cent across capital cities over the quarter compared with 1.5 per cent for units. Melbourne was the only capital where renting a unit was more expensive than renting a house, reflecting demand for well-located apartments.
