Value fashion giant Primark is to open on Edinburgh’s Princes Street after winning planning approval for a 75,000 sq ft store.

Work on the shop, a former Marks & Spencer building, will start as soon as possible and the retailer aims to begin trading in winter 2011.

The flagship store will be Primark’s 18th in Scotland and approval followed months of consultation because of the high profile location and the area’s World heritage Site status.

A Primark spokesman said: “There is great demand for a Primark store in Edinburgh and we expect this decision to approve our flagship store will be welcomed by shoppers and retailers alike.”

Cllr Tom Buchanan, Edinburgh’s convener for economic development, said: “Not only will this development provide a welcome boost to our retail offering, it will create a great many jobs during these difficult times.”

The store has been designed by architect 3DReid. A spokesman said: “The building has been designed to respect the scale and character of a valuable World Heritage Site and the Edinburgh New Town Conservation Area, as well as provide the city with a much-needed catalyst for the retail-led regeneration of Princes Street.”
