The garden will be built by David Dodd's landscape company The Outdoor Room, on the triangle plot occupied last year by Dan Pearson's Best in Show garden.
It will be the Marlborough winery's fourth Chelsea show garden, with last year's design by the Rich brothers winning gold.
It is designed as a secluded retreat to escape from the world. There are no boundaries to the garden increasing a sense of freedom when enjoyed from within.
The primary material is western red cedar timber, used in the construction of a deck, boardwalks and waterside cabin. A large reflective pool adds a sensory element to the design with connotations of setting sail and drifting away.
The planting palette and structure of the garden are intended to allude to the company's signature pinot noir and sauvignon blanc wines.
The Marlborough terroir with its micro-climates and diverse soil types are represented in the planting palette, made up primarily of heathers, pines and grasses. The garden will include a high proportion of nectar-rich heathers and native grasses, which would support a pollinating habitat.
The planting will be punctuated with 'jewel like' surprises such as heath spotted orchids, agapanthus and Potentilla x tonguei.
Ovens, who won RHS Young Designer of the Year in 2014 for his garden at Tatton Park, said: "People love to escape to their gardens. They realign themselves with nature, unearth themselves from a state of mind there. The Cloudy Bay Garden explores a freedom that has no bounds, providing a sense of escape that can take us anywhere.
"I've really enjoyed working with the affinities between gardening and winemaking, and exploring a process which starts in the wild with the earth, and is guided by nature. Similar to the winemaker at Cloudy Bay, my main source of inspiration is the environment, both the natural one and the man made."
Maria Ines Pina, senior brand manager at Cloudy Bay, said Ovens had "perfectly captured the essence of Cloudy Bay" in his design, adding: "This garden is a perfect representation of natural luxury, with Sam's clean lines, serene water and planting providing a place to escape with a glass of wine in hand."
