JPMorgan is to spend £28.6 million to revitalise its Bournemouth Technology and Operations Centre, the firm's operational hub in Europe employing more than 4000 people.
The new spend comes on top of a £10.7 million investment completed in 2011 to upgrade infrastructure at the site.
The US bank says the next wave of investment will transform the infrastructure in the Bournemouth Centre, "creating a more vibrant and collaborative workspace", as it looks to mimic the campus atmosphere created by IT giants like Google in the race to attract top technology talent.
Employees will have access to more state-of-the-art communications technology and office equipment, improving interaction with staff in Europe, the US and Asia. The building's onsite restaurant and common spaces will also be refreshed, and facilities will be upgraded for employees who cycle to work.
The infrastructure projects will be completed throughout the next three years.
JPMorgan has had offices in Bournemouth for 28 years, supporting client activities in 40 countries around the globe.
"Bournemouth offers access to high quality talent and to facilities that can support our business, not just in London, but around the world," says Jamie Dimon, chairman and CEO. "We are proud to be an active member of the Bournemouth community and to be the largest private sector employer in Dorset."
