Quinn Emanuel Urquhart & Sullivan has increased the amount of space it is taking in its London office, and signed up for an option to increase it further in the future.

The U.S.-based litigation powerhouse, which is located at 90 High Holborn in London, currently occupies over 39,072 sq ft across the third and seventh floors of the building. But the firm has recently agreed to take up an additional 11,716 sq ft on the ground floor, representing a 30% increase of office space, its leaders have said.
