Financial services and business advisory practice Cooper Parry is relocating its team to Birmingham city centre.
The company has signed a deal to be the first tenant in the new flexible working hub run by East Midlands outfit Cubo at the £700 million Paradise development.
The Derby-based firm announced last month that it had struck a 12.5-year lease deal for 24,000 sq ft of space within Two Chamberlain Square.
Cooper Parry, which currently has offices at East Midlands Airport and in London, was previously homed on Blythe Valley Park in Solihull.
Cubo was founded in 2020 by husband and wife team Marc and Rebecca Brough and now has co-working facilities in Derby, Nottingham, Leeds and Sheffield with its Birmingham base opening in May. It will have hot desking and designated desk facilities and private offices.
Cooper Parry's chief executive Ade Cheatham said: "Our move into the Cubo space comes at a brilliant time.
"Building on our strong market presence across the region, we have seriously ambitious plans for growth over the coming few years.
"This stunning new base gives us another perfect platform to keep disrupting the marketplace in the West Midlands and beyond."
Mr Brough added: "It's brilliant to welcome Ade and the Cooper Parry Birmingham team to Cubo at Paradise.
"They are one of a growing number of corporate companies which are rethinking their accommodation strategies and moving towards a flexible working model at Cubo.
"Location, great space to work from and flexibility are the main drivers for ambitious businesses."
Other occupiers at Two Chamberlain Square include law firms DLA Piper and Knights, financial services firm Mazars and Rosa's Thai Cafe.
In recent weeks, city planners have awarded consent to a new hotel and public realm work on the 17-acre regeneration site.
