Who are we

The Oliva & Degroise Agency realizes a collaboration of several years between two landscaping professionals. An unexpected meeting of two sensitivities with different horizons, which has, over the course of the gardens created, given birth to a unique and companionable landscape writing.

William, a child of the region, embodies the requirement and finesse of a Provençal landscaping tradition passed down over three generations. With twenty years of experience in the pure realization of gardens, he possesses an instinctive and precise reading of the land, nourished by a deep knowledge of his environment. He perceives every nuance: soil textures, movements of the wind, cast shadows, circulation of water... His sense of detail, demanding and subtle, serves a vision that is fair and deeply respectful of the place. His creativity expresses itself in technical and plant mastery, rooted in the history and diversity of the Mediterranean landscape.

Florian, a graduate of the London College of Garden Design in 2012, received the silver medal at the Manchester Garden Competition in 2013. This experience will shape his relationship with the landscape in a more delicate and emotional approach. From his grandmother's flowery and fascinating garden to the sumptuous and exuberant parks of England, where he will complete his training, he multiplies atmospheres and exercises his curiosity. For more than fifteen years, he invites art and design into his compositions, and his inspiration knows no boundaries. In search of the right emotion, perceived as an obviousness, his creation combines minimalism, originality, and boldness.

Our vision

Our approach is rooted in the Mediterranean art of living. We envision gardens as spaces of understated beauty and embraced simplicity. The golden light of the South, the raw materials, the whisper of the wind in the foliage... these are all elements that nourish our landscape writing. For us, a garden is a place of emotions and memories. Each project tells a story, that of a solar, intimate, and profoundly human way of life. We observe the landscape far beyond the lines of the land.

We listen to it, feel it, and then reinterpret it.

We are sketching a garden that does not simply conform to its location: it interacts with it, draws inspiration from it, and reveals it in new ways. A garden that collaborates, extending the architecture, its environment, and highlighting the personality of the site through the rhythm of life of its inhabitants and their silent desires.

Our mission

Our mission

Our mission

Live outside as inside, with fluidity and comfort, through the seasons. The garden then becomes a space of breathing, as practical as it is aesthetic, where circulation is intuitive, the vegetation chosen with care, and the atmosphere deeply soothing. Each project is thus the result of a subtle balance between place, lifestyle, and creative intuition.

Our realizations exude a form of evidence: that of a space that is just, sincere, and alive. These are gardens that naturally settle into their environment, that accompany the seasons, uses, generations, and that over time become a true extension of the life that unfolds there. A deep anchoring, both aesthetic and emotional.
