Investing further in Bradford, the city which has been its home since the 1930s, Redfern will be relocating to Shire House in Humboldt Street.
The firm’s new home will give the company space for an additional 65 team members with the potential to house up to another 180 in the future.
Mark Bowers, chief executive, said: “After a busy few years we have outgrown our current premises.
“It was important to for us to stick to the company’s roots and find the right location in Bradford, and Shire House is ideal.
“Not only is it central with excellent transport links, it is purpose built and will give Redfern the capacity it needs to continue growing over the coming years.”
Redfern’s move will take place on 21 December.
