About Leonie

Leonie Cornelius is a Garden Designer and Interior Architect who specialises in  customised Garden and Interior designs for companies and brands as well as private clients.

Her approach to gardens is to create a planting palette the same way that an artist would create a painting. Layers of planting create a composition which is always unique and surprising and they tell a personal story for the client. Interested in how gardens impact you on a psychological level, Leonie aims to bring clients a space which is good for the soul, enhances the user’s lives and bring beauty and balance to an often chaotic and ever switched on world.


Writing is another one of Leonie’s passions and her unique design skills and self proclaimed love of sharing creative ideas can be seen in many publications. Her own columns include the Sunday Independent, the Irish Independent Weekend Magazine, Irish Country Living, The Irish Mail on Sunday and The Sunday Business Post as well as many others. Her work has been featured countless times both on the cover of national and international garden and press publications.

Her Show gardens at Bloom in the Park and Chelsea in Bloom have won her numerous Gold, silver gilt, silver   and best in category as well as best planting medals.



Background and Design Path

Born in Monchengladbach in the North West of Germany, Leonie grew up with surroundings of industrial architecture. On a search for a place of beauty to settle,  and some time living on the island of Ithaka in Greece, Leonie’s parents decided to settle on the wild Atlantic coast of Ireland. After finishing school Leonie  initially studied Interior Architecture her design approach is rooted in strong architectural form and clear symmetries. After combining her architecture with a diploma in Garden Design from the prestigious KLC school of design in London, Leonie’s designs place a firm emphasis on combining inside and outside and she believes that there is a vital connection between the two.



Design approach

Leonie intends to bring the highest quality of design both Inside and out and strives to create extraordinary design for the client. As an Interior Architect and Garden Designer, Leonie Cornelius draws inspiration both from the natural prairie planting styles as well as clear architectural lines and symmetries resulting in an exciting synthesis of old and new. Nature and Architecture working in harmony.

The design philosophy is firmly rooted in the belief that purity of beauty and harmony teamed with an ethical and sustainable approach are the highest achievement both within architecture and garden design.
