The firm, which hopes to achieve its grow in the City over the next three years, has leased all of the 32nd and part of the 31st floors at the 20 Fenchurch Street site to house its London-based staff. It has retained additional capacity for future hires.

"We remain committed to growing and developing our regional offerings because our national footprint gives us a significant advantage in the market. It is due to the hard work and commitment of everyone across the business that we are now able to make this investment in the City, giving us an even stronger platform for future growth."

As part of its expansion strategy DWF has grown its 'agile' workforce to over 400 people and has employed over 120 homeworkers. Over the past year it has also invested £11m in its IT systems.

The firm has made 18 lateral partner or director hires in London over the past 12 months, aided by its acquisition of a 50-strong team from Bristol-based insurance disputes specialist Greenwoods in October.
