garden design
with
designing nature
Every garden design grows from an attentive dialogue — with both the people who will use the space and the natural qualities of the site. By observing how a place behaves and understanding what people need from it, each design becomes a thoughtful response to both.
Whether subtle or expressive, every garden is rooted in care for the environment and the way we live in it.
​Hello,
I’m Olga Hart, garden and landscape architect .
​​​
At Hortus Quo, I design outdoor spaces
that feel natural, thoughtful, and made to last.

VISION
Sustainability for the future
I want to create designs that still make sense years from now. That’s why I choose native plants, use water sparingly, and work with materials that have minimal impact on nature. In doing so, I hope – in my own way – to contribute to a world that remains livable.
Biodiversity
I love giving nature space to be itself. . I leave room for wild edges, blossoming meadows and quiet growth—where biodiversity isn’t controlled, but celebrated.
Waterinfiltration
Nature and people in harmony. In my designs, the balance between the two is central. That’s why I use materials that allow rainwater to infiltrate and foundations that keep the soil breathable. This way, I create places that remain a healthy living environment — today and in the future — for all of us.
Art as a finishing touch
Art objects add an extra dimension to your garden. They create eye-catchers, stimulate fantasy and bring personality into your outdoor space.

​
Each garden starts with the place itself — its light, soil, rhythm, and potential. My goal is to create spaces that not only look good, but feel good to live in.
With a clear structure, well-chosen materials, and planting that evolves with the seasons, I aim for gardens that are personal, grounded, and quietly beautiful.

Introduction meeting
During an initial introduction, expectations are tested and the garden is viewed and measured on the spot.
Preliminary design
A first proposal (2-3 options) is elaborated and discussed together. All comments and choices are adjusted in the plan.
Final design
The final design includes a visual 2D plan with materials and dimensions, with an optional detailed planting plan and 3D sketches.
