But now the rise of online retailing is fuelling demand for last-mile logistics all over the UK, so is the golden triangle as relevant as it once was?

The phrase ‘golden triangle’ was first coined in the late 1980s when it referred to an area of around 80 square miles bounded by the M1, M6 and M69. “It was a really small triangle right in the middle of the East Midlands and with great connectivity,” says Jon Compton, head of logistics strategy at CBRE. “It wasn’t a big area and it was dominated in terms of logistics by Magna Park at Lutterworth.”

The area has expanded hugely in the last 30 years. The location now generally referred to as the golden triangle encompasses some 550 square miles, a seven-fold increase. However, it appears the definition is still evolving.
