Asda is looking to open 300 smaller stores, between 15,000 sq ft and 30,000 sq ft, in the UK after successful trials in Bodmin, Cornwall, and Walthamstow, North London.

Chief executive Tony De Nunzio has said he wants to create high street stores in small towns where the group would be unable to obtain planning permission for its larger sites. According to The Times 15,000 sq ft was the smallest store size that would enable Asda to maintain its low-prices strategy.

De Nunzio added that Asda would like to include non-food items at the smaller outlets and said it could use technology and expertise from Wal-Mart to help maximise range in a small space.
