SDC Philosphy

Sydney Design Collective (SDC) is a landscape architecture practice that thrives on collaboration. Anchored by Director David Duncan, SDC includes a network of partners and consultants with years of industry experience and expertise. 

Every project we undertake is individual and requires its own landscape solution. 

Our work methodology has been applied to Green Buildings, Civil and public domain, community projects, large residential blocks and urban towers in the major metropolitan centres of Australia’s east coast.

We love modern, site-specific design that incorporates function and aesthetics. 

Let us help you create liveable, sustainable, long-lived and beautiful spaces.



The Collective

We are a flexible, modern network without the overheads of a traditional company. We embrace the freedom of the digital workplace and evolve and adapt on a project by project basis. We only use a physical office space when needed allowing us to work onsite or remotely where required. For large or complex projects, we expand our team by drawing on our collective of leading specialists.
