About Katerina Kantalis Garden Design
Katerina Kantalis is a RHS Gold Medal-winning garden designer based in South East London, creating naturalistic gardens across London, the South East and the wider UK.
As the only Greek-Australian garden designer practising in the UK, her work draws on Mediterranean and Australian design principles — bringing Mediterranean warmth, natural materials and drought-tolerant planting to British gardens.
Her work is shaped by a simple but deeply held belief: that a well-designed garden changes how you live at home. Every project balances structure, planting and atmosphere, guided entirely by the people who will use it.
Alongside her residential practice, Katerina has earned national recognition for her show gardens, winning Gold medals and Best in Category awards at both the RHS Chelsea Flower Show (2026) and RHS Hampton Court Garden Festival (2024). These achievements reflect her commitment to gardens that combine strong design, exceptional planting and a distinctive sense of place.
From compact city terraces to larger residential landscapes, the approach is consistent: bold in composition, naturalistic in planting, and shaped around the life lived within it.
Where it all began.
The roots of the studio. Grounded in nature, growing through design.
-
Originally from Adelaide, Australia, Katerina grew up as a first-generation Greek-Australian. Her childhood garden was filled with fruit trees, vegetable beds, beehives and open space. A suburban plot shaped entirely by her parents' Greek roots, and the place where her love of growing began.
After moving to the UK, she built a successful career in science and fundraising, earning a PhD, before retraining at the British Academy of Garden Design in 2020.
In 2021, she founded her South East London practice, bringing together analytical thinking, creative vision and a design philosophy rooted in two cultures, two climates and a lifelong connection to the outdoors.

Katerina's work is rooted in the belief that a well-designed garden should feel like it was always meant to be there.
Every project is shaped by the architecture of the home, the character of the site, the lifestyle of the people who use it and the long-term growth of the planting. Nothing is generic. Nothing is dropped in.
The result is a garden that encourages you to spend more time outside. Somewhere to entertain, to unwind, to simply be. Timeless, balanced and uniquely personal.

Planting is central to every project.
Katerina designs gardens that support biodiversity while remaining elegant and structured. Every planting scheme is developed with careful consideration of soil conditions, aspect and seasonal change — so that gardens continue to evolve beautifully over time.
Material choices and permeable surfaces are considered with the same care, supporting both sustainability and long-term durability.
The result is planting that looks effortless. Because the thinking behind it isn't.
