There are multiple grids that make up the modern city, these are networks of different types. Some, like the power or transport grids exist and are accepted, utilized each day and only questioned when they fail. Some, like the Green Grid are tangible and close to what people know, but are as yet not regarded as essential like power or water. Others like the Ochre Grid or Ecological Grid are barely legible, containing culture and life of the landscape within their deep memory.

There is an opportunity to draw the unseen grids into the tangible experience of place, remaking a deeper connection to country for citizens of modern Sydney. Beyond a simple link or spatial connection, a revived culture of ecological system stewardship and Caring for Country can and should be inspired by the design of the public face of the city.

This idea can be realized only through precise strategic system connectivity at a city scale, linked seamlessly to seductive composition and form at a site scale. This proposition outlines a design process Tyrrell Studio are developing.

This process organizes city scale grids with clarity through sieving and thinning of mega spatial data, whilst at the same time thickening the layers of the meaning of landscape through collage, overlay and citizen engagement. Surfaced through this process are possible connection points between site and system to catalyse major urban and cultural transformation.

Unbuilding Utopia

With our cities changing more rapidly than ever before, especially post-pandemic, we face complex design problems that are larger than one building or one solution. Unbuilt work, says Mark Tyrrell, has the ability to link spatial visioning in a new way with the complex social, political and cultural reality of the evolving city.


We use design competitions to explore ideas and test new research. Some of our winning entries have resulted in productive client relationships, providing the opportunity to further develop the ideas and test them in practice. We are continually searching for catalyst projects to challenge the status quo and demonstrate new thinking.
