About
Lionel Ely-Marius, garden designer.
I design calm, planting-led gardens for homes in London and the Home Counties, and see every project through from the first conversation to the finished garden.
My story
Rooted in Martinique, growing gardens in London.
I grew up in Martinique, and that is where my love of plants began. I am deeply inspired by the luxuriant landscapes of my island: the layered canopy of the rainforest, the density of life, the way everything grows together in balance. That abundance shaped the way I see gardens, as living places that should feel generous, calm and full of life, and it is what I try to bring to every garden I design.
I trained in garden design at Capel Manor and the London College of Garden Design, and founded Green Oasis Design in 2021 to bring together the two things I care about most: horticulture and design.
Martinique · where it began
The rainforest taught me how generous a landscape can be.
How I work
One designer, from first sketch to final plant.
When you work with Green Oasis Design, you work with me directly. I listen to how you want to live in your garden, design it in detail, and stay involved while it is built.
For construction and planting I work with a trusted network of landscapers, craftspeople and nurseries, chosen for the quality of their work. I coordinate them and visit the site so the finished garden matches the design.
01
Listen first
Every garden starts with you: how you live, what you love and what the site allows.
02
Planting-led
Plants are the heart of my designs, chosen for structure, scent and interest through the seasons.
03
Designed to last
Sustainable choices that support wildlife and grow richer, not harder, to look after.
“Lionel transformed our garden and delivered the vision we had of a peaceful oasis in central London, despite deep shade in some areas and full sun in others. The result is perfect.”
