2026 Speakers

Luciano Giubbilei
Luciano Giubbilei began his career in gardens when he moved from his birthplace, Siena, to London in 1994. By 1997, he had completed his studies at the Inchbald School of Design and established his own practice.
This practice has evolved with a defining emphasis on exploring and nurturing a sustained dialogue with artists, architects, plantsmen and craftsmen. It is this commitment to collaboration that Giubbilei believes is key to expanding and challenging the creative process, moving the practice from the limitations of a familiar language.
Giubbilei began working on his experimental border at Great Dixter in 2012, after a transformative residency working alongside head gardener Fergus Garrett. This experience inspired a shift, encouraging an exploration of planting possibilities that has lead the studio towards larger landscape projects in Europe and the US. This evolution is documented in his most recent book, the Art of Making Gardens.
The studio is recognized for the understated elegance and serenity found in the gardens we create; defined by light and influenced by the classical Italian design heritage of proportion and balance. The gardens evolve through an exploration of spacing, rhythm and the repetition of single elements. Our motivation is to create timeless spaces, multi-layered environments where culture and nature are in close communication. Our approach is constantly evolving, both in response to individual clients and to the unique site characteristics. We strive to forge an emotional connection between the place and the people, valuing local materials and expressing our desire to connect people to nature, not merely through plants and flowers, but through the spatial arrangement, and its beauty.
