What you want to do in the public space and why?

Install a greenwall on one wall on the proposed sites listed below:

Vertical greenery transforms unappealing spaces by bringing natural amenity into the city environment. A growing body of evidence supports that communities are healthier when there is greenery and connection to nature. Vertical gardens can reduce wall surface temperature by up to 12° Celsius. This helps in reducing heat island effect. Green walls are a proven way to reduce traffic noise while improving air quality and liveability. That means a Darwin city environment with a lot more happy birds, bees, visitors and locals.

How you will make this project happen?

Installation of the green wall is relatively easy to action as the process we will use is a simple matter of mounting fixed modular units to the outdoor masonry with a waterproof backing surface and a water wise irrigation system.

When will the project start and finish? How long will it take?

Installation would only take a few days on site and would be best to do towards the end of the wet season in April. Vertical gardens live for many years and it is envisioned that the project delivery will provide inspiration to result in more green installations applied to other Darwin city buildings improving the amenity of the CBD area.

What permits or whose permission will you need to implement the project? What do you already have and what will you need to obtain?

The Reserve Bank building is government-owned and heritage-listed and already has signage and large scale tourism imagery installed on the outside of the building that a green wall garden would complement and use similar fixing infrastructure to adhere the grow panels to the concrete façade. The heritage permissions already granted to allow current signage and large scale poster panels to the front of the building would indicate NT Heritage Branch permissions would be expected to be granted for a similar installation to the exterior of the building.

The Local Court House is NT Government-owned and Government has already shown a commitment to greening City areas with the delivery of the nearby Cavanagh Shade Structure so it could be expected a project like this that increases Greenery in the CBD would also gain NT Government permission and support for installation.

The Sky Bridge is NT Government-owned and Government has already shown a commitment to greening City areas with the delivery of the nearby Cavanagh Shade Structure so it could be expected a project like this that increases Greenery in the CBD would also gain NT Government permission and support for installation and traffic management permits.

The Convention Centre is NT Government-owned and Government has already shown a commitment to greening City areas with the delivery of the nearby Cavanagh Shade Structure so it could be expected a project like this that increases the natural amenity of the Waterfront would also gain NT Government permission and support for installation.

The Chinatown carpark is City of Darwin-owned and already has signage and large scale framed artworks installed on the outside of the building that a green wall garden would complement and use similar fixing infrastructure to adhere the grow panels to the concrete façade. The City of Darwin recently declared a state of climate emergency so it could be expected a project like this that reduces carbon emissions would gain council permission and support for installation.

How will you deliver the project, including how many people will be involved and any partnerships you have developed?

Greenwalls of Australia is a new initiative of a group of local Darwin business people already involved in delivering landscaping, stonemasonry and exterior and interior design projects. With Singapore being a leader in green building systems, we have partnered with an established award-winning Singaporean green engineering company to implement their range of established vertical garden products that have already proven successful in use for many projects including at Changi Airport and the Singapore Zoo. In Darwin, the 4 person team to install the green wall will be made up of locals, including one indigenous staff member.

How will you know your project is successful?

Cities such as Singapore and Manila that have similar climatic conditions as the Top End, are already improving liveability and reducing heat in city areas through innovative green installations. Green buildings are a win-win for businesses and the environment. Singapore’s ‘garden city’ approach has shaved 11.6% off total operating expenses of buildings while also reducing carbon emissions. By giving life to new green infrastructure solutions in the Darwin city environment such as this project, it will help encourage greater change and vision for local building developers to rethink urban designs through innovative and sustainable architecture investment that complements our climatic conditions.
