The firm, which has stores in Harrogate, Hexham, and York, is set to move into one of three new units made up of the former H&M.
In recent weeks, new signs have been erected on the front of the store teasing the brand to shoppers – with a string of new jobs now also up for grabs.
The new 1570sq. ft store will offer an extensive range of women’s and men’s clothing, as well as accessories and gifts, all of which will feature White Stuff’s unique designs.
White Stuff, which designs all clothing prints in house inspired by everything from fine arts to architecture, will also sell its upcoming autumn collection from the new store once open.
The confirmation comes just several months after the chain first appeared on since-updated park plans, drawn up by British Land, in May.
Now, four new jobs have been posted online for the store, including two supervisors (12 hours and 16 hours), a deputy manager (37.5 hours) and store manager (37.5 hours).
White Stuff is the latest in a line of new brands to join the packed shopping complex, following the openings of Primark, Nike, and Ninja Warrior this year, and the likes of Wagamama, Lush, and B&M in 2023.
There are also plenty more openings planned later this year and into 2025, including a new Sports Direct and Flannels store, Mango, Rituals, and PureGym.
The Teesside store is the fifth of a number of planned openings for White Stuff, which was first established in 1985, this year.
Catherine Furlong, centre director at Teesside Park, said: “We promised to reveal more amazing new brands throughout the year, and I’m so pleased to confirm White Stuff as the latest addition to Teesside Park.
