Since M&S entered the forecourt retail sector, the design and development of sites has become more important than ever. So says Mathew Fleming, head of programme management at retail fit-out specialist, Barlows. "Marks & Spencer's decision to roll out its Simply Food offer at BP filling stations has raised the bar and meant fuel retailers are competing not just with each other but with the high street. Design and branding is more important than ever and many will be forced to rethink their offer if they want to retain customers and increase market share."

Its forecourt is made from concrete mixed with pieces of recycled glass; its roof has 90 solar panels; and it uses low-energy lighting. However this is not some space-age prototype but a fully operational BP forecourt trading in Los Angeles.
