Taylor Cullity Lethlean

TCL is one of the world’s most highly acclaimed landscape architecture and urban design firms.

Over the past 25 years, we have delivered a wide range of projects across a variety of public and private settings, from urban waterfronts to desert walking trails. We work both nationally and internationally, undertaking a detailed exploration of context, site and community, with a focus on the poetic expression of landscape and contemporary culture.

Four streams of investigation have informed TCL’s work:

  • contemporary urban life and global culture
  • the elemental power of site and landscape
  • artistic practice in a range of disciplines
  • the creation of a sustainable future

Through a dynamic and collaborative dialogue with clients, communities, academics, and colleagues, we have delivered an eclectic body of work that speaks of quality, commitment, beauty and richness. This is achieved within real world constraints of time, management and cost.

TCL is Australia’s most awarded landscape architecture firm, having won over 120 awards in the past 25 years. We have twice been awarded the prestigious ‘Landscape of the Year’ award at the World Architecture Festival for the National Arboretum Canberra (in collaboration with TZG Architects in 2014 and the Australian Garden in collaboration with Paul Thompson) in 2013.

In 2014, TCL was awarded the highly coveted 8th Rosa Barba Award at the International Biennale of Landscape Architecture Barcelona for Auckland Waterfront, New Zealand in collaboration with WA Landscape Architects.

We bring to each project the following:

Robust and Meaningful Visions

TCL is renowned for developing masterplans and conceptual designs that respond to their context and provide compelling visions for the future. Designs that are embraced and owned by all stakeholders.

A Collaborative Approach

We are highly recognised for our love of collaborating with clients, stakeholders, communities, academics, artists, and other consultants. We value and respect difference and diversity.

An Ecological Base

We have worked creatively with environmentally sustainable principles since the company’s inception. We embrace sustainable practices in all of our projects to minimise the ecological footprint and maximise integrated environmental systems such as water sensitive urban design (WSUD).  

Sustainable Communities and Economies

TCL has always maintained a strong community development focus with stakeholder consultation being an important part of the practice’s approach to projects. We also recognise and have a keen awareness of the importance of creating sustainable economic outcomes for our clients.


Our practice is committed to undertaking ongoing research and has a dedicated research arm known as Tickle. Tickle speculates on the future of the expanding field of landscape architecture and urban design, and challenges existing paradigms. In addition Directors Kate Cullity and Perry Lethlean have recently completed PhD studies which explored undercurrent themes of TCL’s design practice.
