Built environments are becoming so complex that they’re creating their own micro-climates. They have distinctive processes, including water and wind flows, light and shadow paths, temperature cycles etc. Built environments have similarities with certain ecosystems in the natural world, from which valuable lessons can be gained through biomimicry. For example, the architecture of Federation Square has similarities with the landscapes of central Australia. The plant communities of central Australia could inform a planting design strategy for this urban landscape.

The idea is to explore what built surfaces plants can grow on. Identifying suitable growing mediums and water regimes are two key challenges. Prevailing drought conditions and water restrictions mean that plants need low water requirements. Furthermore, the diversity of surfaces in built environments, from horizontal, diagonal and vertical, as well as accessibility issues means that setting up irrigation systems and soil substrates can be difficult. This is why native plants need to be studied to see how they cope with these problems in the natural landscape.

Thinking about architecture as a new topography is not about creating gardens as much as creating ecosystems that act as environmental infrastructure, specifically tackling the issues of urban water management, heat island effect, passive solar design, habitat corridors etc. The intention is to create more livable built environments, for humans and animals alike.
This approach will provide people with opportunities to interact with nature, offering something more than the material world, something spiritual. (Ellis Stones) It also means that architecture and landscape need to be considered as two aspects of the same environment, and inevitably should be designed simultaneously.
We will need to think about the built terrain in new ways as urban environments become more consolidated to support growing populations. Infiltrating cities with ecosystems needs to be considered with other goals such as decreasing car-dependency through public transport use and designing for pedestrians and cyclists.

This is an opportunity to go beyond the limited views of plants as mere decorations and explore their other uses for food, medicine, timber, textiles, and water/air/soil managers.
