Daylesford Organic, the Gloucester-based 'farm shop' business run by the Bamford family, which owns JCB, opened a store on London's Pimlico Road this week.
Billed as "a breath of countryside in London" the three-storey store has a total selling space of 4,500 sq ft, making it the chain's largest outlet, and features a range of fresh and seasonal organic fruit and vegetables, as well as meats, cheeses, cakes and breads.
Products are ranged on large white marble counters to create a premium look, but also to help conserve energy by keeping foods naturally cool.
The new store also has a large café, glass-fronted kitchen and an underground cellar where a third of the wines are organic or biodynamic - ie adhere to a strict form of organic production.
"As with everything that we do, we are reviving the traditional and preserving precious artisan skills in the new store," a company spokeswoman said. "For example, our master bakers will be baking bread using an oven clad in our own dry-stone walling."
Daylesford Organic currently has a shop and café in Gloucestershire, a café in Sloane Square, London, and a concession within the food hall at Selfridges, London.
