The Alphabeta building in Worship Street, Finsbury Square, will give We Are Social more room to create areas that it says are more suited to its work.
The new office is over two floors and covers 27,000 feet. It has three bespoke photo and film studios, allowing We Are Social to work on professional photography, animation, and film work. There is also an event area which will be used for seminar and speaker events.
We Are Social currently has 150 employees and is looking to fill a further 15 positions, all of which are due to move into the new building.
The move follows a number of agencies which have moved, or are about to move, to a new address. A number of Omnicom agencies have moved to the former Royal Bank of Scotland office in the South Bank, close to where Ogilvy & Mather's new premises will be at Sea Containers House.
Jim Coleman, the managing director at We Are Social, said: "The move to the Alphabeta building reflects the beginning of another chapter of We Are Social’s growth.
"We’ve designed our new space by listening to our teams about what environment they need to be amazing at their jobs, and what our clients expect from a forward thinking agency.
"We've been creating fast turnaround film, animation and photography content for all of our clients over the last three years, and our new space will allow us to do more of this at scale and involve our clients in the process."
