Bond Pearce has begun a restructuring programme that will see it close its Exeter base and transfer 60 staff to offices in Plymouth and Bristol.
The cost-cutting measure, which will not lead to any redundancies, coincides with the firm's move to new City premises in July.
Bond Pearce managing partner Victor Tettmar said the firm was streamlining costs in a bid to increase turnover to £100m within the next three years. In the last financial year the firm's revenue was £47m.
Tettmar said the Exeter closure would not have a major impact, adding that it was not necessary to have two offices in Devon.
"Primarily this is about growing our team from a single office in Devon and being able to act for the most important clients in Devon and nationally," he added. The firm is no stranger to restructuring, having shed 25 lawyers from its personal injury practice in 2006-07. As a result the firm's average profit per equity partner figure, which dropped 17 per cent in 2006-07, rose 63 per cent in the last financial year.
