Business growth has forced AXA Art Insurance to find new London offices.
UK chief executive Adam Golder said: "We are not just on the move to new offices. This reflects the strides we are making in the business.
"Our office will actually have two front doors so we see this as a symbol or our determination to double our income."
From 17 December, the company will be based at 106 Fenchurch Street, London, EC3M 5JE. There will be a separate entrance through 52-54 Leadenhall Street.
The company's new telephone number will be 020 7265 4600.
In total, AXA Art has twelve offices in Europe and four in the US.
