Urbanism That Coexists with Nature
Nature Positive Urbanism
Bringing together urban design, ecological planning, and regenerative investment to deliver futures that serve both people and planet.
Shaping cities where nature and people thrive together.
Sharp Day is a global urbanism and ecological design consultancy helping governments, developers, and communities deliver places that are resilient, biodiverse, and future-ready.
Formerly Sharps Track, we bring decades of experience in urban strategy, placemaking, and regenerative land practice. Our work centres on Nature-Positive Urbanism, going beyond “minimising impact” to actively restoring ecological function within every plan, precinct, and project.
We integrate biodiversity, landscape-led design, and circular systems into the foundations of new neighbourhoods, regional frameworks, and city-shaping visions. From greenfield communities to complex regeneration sites, we help our clients design urban environments that are inclusive, climate-adapted, and ecologically alive.
Recognised by national leaders in sustainability and urban development, Sharp Day brings integrated expertise across urban design, ecology, and impact capital to deliver cities that restore, regenerate, and reconnect.
What We Do
At Sharp Day, we work across scales and geographies to create places that are ecologically regenerative, socially inclusive, and economically resilient. Our projects range from new neighbourhoods and greenfield townships to regional strategies and transformative urban frameworks.
What unites them is a commitment to walkability, biodiversity integration, and long-term place stewardship.
We don't build projects. We build living systems of place.

Who We Are
Sharp | Day is a consultancy specialist shaping places where nature and neighbourhood co-exist in harmony.
Co-founded by biodiversity investor Nigel Sharp and urban designer Mike Day, Sharp Day sits within a wider ecosystem of nature positive initiatives and regenerative investments, including Tiverton Agricultural Fund and Dragonfly Enviro Capital. Together, Sharp Day turns ecological ambition into practical, investable urban outcomes.
Nigel Sharp is an Australian biodiversity impact investor, conservationist, and business innovator who has spent over 15 years building nature-first companies that deliver measurable benefits for both the environment and communities.
Starting his career in property and fund management—culminating in the ASX listing of a $300M property trust—Nigel returned to his passion for conservation in 2001. His work includes establishing Mt Rothwell, Victoria’s largest feral predator-free ecosystem, and developing The 7Cs Impact Framework, which balances commercial returns with outcomes for creatures, climate, corridors, community, and culture.
Today, Nigel leads several organisations dedicated to proving that profitability and biodiversity can grow together.
Mike Day was a co-founder of Roberts Day for 30 years and more recently a partner at HATCH | Urban Solutions, where he helped shape award-winning new towns and urban renewal projects across Australia, New Zealand, the UAE and Asia. Best known as the principal master planner of Ellenbrook New Town, Mike has also led the master planning of the CLARA High-Speed Rail and new city strategy business case for the Australian Federal Government, and has served on planning authority boards and industry committees in both Western Australia and Victoria. A Fellow of the Planning Institute of Australia and the Australian Institute of Company Directors, Mike was also the 2018 recipient of the Place Leaders Asia Pacific Award for Leadership in Walkable Urbanism, and remains passionate about creating places that are more walkable, more liveable, and more nature-positive for future generations.
Our Ethos
Our ethos is grounded, practical, and future-focused design cities that make life better - for people and for the planet.
Our approach is to weave ecology into the core of urban design. This means considering how streets connect, how blocks are shaped, and how green-blue systems flow through a place - all in ways that support people, climate, and biodiversity.
We harness proven urban principles such as walkable neighbourhoods, mixed uses, and strong public spaces, paired with landscape science, native biodiversity, and climate resilient design.
The outcome is simple, yet sophisticated - places that are low-carbon, biodiversity rich, highly liveable and built to endure.
Sharp Day is not just as an advisory consultancy, but a larger “climate-forward movement” - one that connects:
· landscape ecology
· regenerative and impact-led investment
· enduring design principles
· and urban form that strengthens natural systems
Our Services

We work across urban design, ecological planning, and regenerative investment, delivering solutions that move beyond short-term outcomes to create enduring value. From reimagining urban systems to advancing biodiversity, we bring research, creativity, and collaboration together to craft futures that are resilient, inclusive, and grounded in nurturing the planet.

We believe the future of cities depends on their ability to regenerate nature while supporting resilient, walkable communities.
That’s why every Sharp | Day project is underpinned by our three-part approach:
Our Approach
Ecological Integration
We begin with the land. Its systems. Its memory.
We map and protect native habitats, restore biodiversity corridors, and embed green-blue infrastructure that does more than drain—it nurtures.
Our designs respect landscape logic: ridgelines, wetlands, tree cover, and soil health aren’t afterthoughts—they shape the settlement structure itself.
We design neighbourhoods—not subdivisions.
Neighbourhoods with walkable blocks, human-scaled streets, diverse housing, and active public spaces.
Inspired by proven timeless nature positive urbanism, design principles, and contemporary needs, our work connects people to daily life without dependence on the car—and connects streets to habitat without sealing them off.
Human-Scale Urbanism
Resilient Futures
Climate readiness, economic diversity, and social inclusion guide our decisions.
We model carbon impacts. We think in generational timeframes. And we work with clients to embed affordability, circular economies, and place-led stewardship from the outset.
Whether designing for growth or regeneration, we ask: Can this setting sustain life—for all life—for generations?
Thinking Beyond the Brief
Sharp | Day is more than a consultancy, we’re a platform for advancing the future of urban settlements and nature.
This is where we share what we’re learning, questioning, and championing—from new planning models to global case studies, biodiversity research to walkability metrics.
