Arit Anderson 

Arit Anderson is a garden designer, writer and presenter on BBC Two's Gardeners' World. She spent 25 years working in the dynamic industries of retail fashion and creative events. She managed teams that delivered collections and events across the globe. She balanced this fast-paced career with interests in well-being, working as a therapist and teaching holistic therapies, which led her to travel extensively to the USA. It was the joy of having her own garden that enabled Arit to diversify her creative experiences. She found that the visual nature of fashion and the healing properties of her therapies could beautifully meld in the garden.  Playing with a new palette of colour and materials in her garden, drove her to explore the unique relationships between her love of plants, people and place. After just one season, Arit knew she wanted horticulture to become her work as well as her pleasure. She studied gardening at Capel Manor College and whilst there had success at RHS Chelsea 2013 winning the Fresh Talent category for a student design collaboration with two other students. After attaining a diploma in garden design, she won a Gold Medal for her own design at RHS Hampton Court in 2016 in the conceptual category.  In her designs for both private and commercial clients her ethos includes simplicity and environmental sensitivity – affecting her choice of products and plants at source, with regard to their future setting. Working as presenter for Gardeners’  World and writing for national publications has enabled Arit to publicise issues about the future of gardening in an ever-changing climate, and promote solutions to the wider public. 


Andrew Duff MSGD

‘Having spent my childhood growing up in the English countryside, I studied garden design and writing in London which seemed a natural progression to my love of everything creative.’  After graduation Andrew cut his teeth with The White Dutton Partnership before joining the late John Brookes as his Associate Designer. ‘Brookes taught me how to look; he had a great skill for reading a space and listening to the client.  I use this to learn from the local vernacular treating each garden as if it is my first design.’  In addition to running his practice, Andrew is Managing Director of the world renowned Inchbald School of Design and Vice Chairman of The Society of Garden Designers.  ‘I am passionate about teaching, in particular the communication of the design process.  Nothing pleases me more than seeing a student master a complex design to the delight of their client.’  Andrew enjoys designing a wide spectrum of gardens, be it a small city space or a large sprawling country estate.  As an internationally recognised garden designer, Andrew has lectured and taught in Russia, Chile, Argentina, South Korea and Japan. ‘Having designed gardens for over 25 years I have been lucky enough to work close to home but also internationally.  More recently the studio has completed designs in Surrey and India. It is this versatility of the differing vernaculars that I find incredibly exciting.’

Bernard Trainor

Bernard arrived in Northern California in 1995 and soon after fell in love with this land. He is the founding principal and creative director of Ground Studio. Drawing on thirty-five years of passionate commitment to the study and practice of landscape design, he is involved with his collaborative studio team on every landscape project from conception to completion. Throughout the years, he has completed four academic programs, practiced professionally in three countries, and continues to lecture extensively on the subject of Landscape Design throughout the world. His award-winning projects range from small gardens to extensive rural properties, and have been featured in a wide range of books and publications throughout the world including the New York Times, Vogue Living, Garden Design, and two monographs solely devoted to the studio’s work published by Princeton Architectural Press. Bernard was raised on the Mornington Peninsula along Australia’s rugged Southeastern Coast, not far from the city of Melbourne. It was here that he developed a lasting awareness and appreciation of the native landscape that led to horticultural and design studies. Following an apprenticeship, he was awarded a scholarship that allowed him to move to England and study under the famed plantswoman and garden designer Beth Chatto. Her regionally appropriate planting designs further developed Bernard’s design philosophy and subsequently the direction of his landscape designs that followed. Her influence was significant. In the years that followed, Bernard then completed a Diploma of Landscape Design while studying at the Chelsea Physic Garden. In practice, the geographical diversity of his educational and work experiences cultivated a deep appreciation for California’s unique regional qualities and culture. “Whilst traveling I soon discovered my favorite art, architecture and landscapes are deeply connected to the place from which they have ‘grown”. This simple observation and a keen awareness of the regional context inform every design project

During this time, he graduated with distinction from the Master in Landscape Architecture program at the University of Greenwich. Giacomo’s passion for plants began in his youth. His experience working in nurseries across Italy and the Netherlands offered an opportunity to explore this interest further and subsequently influenced him to pursue a career as a landscape designer and horticulturist. At Gillespies, Giacomo has developed an impressive and richly varied portfolio of urban landscapes, ranging from landscapes and planting compositions for several prestigious residential and mixed-use developments through high-profile public realms in London and internationally. Giacomo has a naturalistic planting style, combining plants to create habitat-specific planting mixes that suit each scheme’s specific character, use and environment. He aims to develop resilient and biodiverse plant communities that will evoke joy and curiosity, encourage wildlife and meliorate the effects of a climate change. In Gillespies’ London office, Giacomo leads the planting research group, organising plant tests, planting focused visits and talks. He also provides advice and support to staff across the practice on planting specifications for both UK and international projects. In addition to his professional practice, Giacomo is an academic tutor in planting design at the University of Sheffield and an external lecturer in planting design at the University of Greenwich and at the KLC School of Design in London.

John Little 

John argues against long standing protocol within public space and horticulture. He suggests structural complexity is overlooked in landscape design and is more important than plant choice Since starting the grassroofcompany in 1998 he has designed and built over 300 small greenroof buildings, combining deep biodiverse green roofs with walls of breeding and hibernation space. After 18 years caring for the greenspace on Clapton Park estate, Hackney, he produced a sustainable grounds maintenance contract that puts people first. He questions our obsession with specifying top soil in all new projects, especially on highways and new developments. Habitat trials at his home include a garden designed with spoil from the local road widening scheme, industrial and construction waste In 2008 he launched a range of small green roof shelters based on shipping containers and designed portable structures including bike and bin storage.
