Rooftop gardens or sky gardens are adorning more and more rooftops across the globe—benefitting the communities that lie beneath.

Landscape architect, Sara Padgett Kjaersgaard, UNSW Built Environment, says that rooftop gardens make for beneficial green spaces in major cities.

Padgett Kjaersgaard said that green spaces are essential to the health and wellbeing of residents—especially those residing in apartments that have no backyard. 

Aside from their aesthetic value, rooftop gardens often come complete with public seating, BBQs, fruit and vegetable patches, etc. This is a place where folks socialise, and that promotes ecofriendly building by retaining stormwater, cooling the roof temperature, reducing the energy consumption of the building, and reducing the urban heat island effect by devising a cooler microclimate. 

Rooftop gardens are also healthy, giving people needed nearby green space in which to rest and destress.

And for developers, it only makes sense to supply more greenspace to residents.

However, Australia lacks solid mandates for green rooftops for new buildings. And laws mandating the retrofitting of rooftop gardens on older structures are not in place.

We need green roofs atop social housing as well, said Padgett Kjaersgaard, and they must be well-maintained.

She says, further, that we require green street-tree canopies, connected to public open spaces, interconnected to green roofs to create a green grid.

The landscape architecture business is lobbying for a suite of green infrastructure to be a feature of national policy via Infrastructure Australia’s Priority List. And, says Padgett Kjaersgaard, we all have to push for and promote this concept—shouting the concept from the green rooftops!
