The retailer is working with owner Intu to transform a former Sainsbury’s into one of Next’s largest stores in the UK.
The offering, which will include womenswear brand Lipsy, a full homeware offer and a coffee shop, is scheduled to launch next spring.
Intu regional director Nick Round said: “Next’s significant investment at Intu Merry Hill reflects our own long-term commitment to the centre and the confidence that exists in it as a destination where brands can really flourish.
“Our plans are to attract even more great brands and create compelling experiences for customers across the West Midlands.”
A Next spokesperson added: “We’re excited to have secured this fantastic space within the prime retail destination of Intu Merry Hill as the site of our next West Midlands store.”
Brands including JD Sports, Topshop and River Island have invested in increasing the size of their stores at Intu Merry Hill during the past year.
The shopping centre attracts 22 million visitors per year. It will be fully refurbished as part of plans to invest £100 million in its retail and leisure offering.
