Harvey Nichols is to more than double the size of its Birmingham store and relocate it within the city’s Mailbox shopping complex.

The department store will be relocated from a smaller unit in the centre and redesigned to a new 45,000 sq ft store. It will extend its menswear and personal shopping offer after the departments enjoyed strong sales in its existing Birmingham store.

The departments will sit alongside its womenswear, beauty, accessories and food sections. The store will also feature an extended hospitality offer.

The Mailbox’s wider redevelopment will also introduce an improved, pedestrian-friendly public space that will span the underpass beneath Suffolk Street Queensway to the front of the development.

Harvey Nichols group chief executive Joseph Wan said: “We firmly believe our participation in this redevelopment will underline our commitment to Birmingham and its shoppers – it is a testimony to our success in the city as well as the success of the city itself.

“The new store will enable us to greatly expand for our customers the best of fashion, beauty, accessories and food and to continue bringing them the very best in luxury and service well into the future.”

Harvey Nichols has stores in London, Leeds, Birmingham, Edinburgh, Manchester and Bristol in the UK, Dublin in the Republic of Ireland and internationally in Saudi Arabia, Hong Kong, Dubai, Turkey, Kuwait. It is soon open in Azerbaijan.
