Continued expansion of the investment management firm's international business has led to the need for increased office space in London.

Brown Advisory has moved its London-based team to larger office premises in Hanover Square following the expansion of its international business.

The firm's previous London office, established by Logie Fitzwilliams (pictured) in 2008, now comprises 75 staff, with client assets standing at $20 billion (£15 billion).

The firm has two other international offices including its Singapore office which opened in 2019 and its Frankfurt office launched last month.

The new Mayfair office enables the team to work together on one floor and reflects its commitment to sustainability – the new offices have been awarded a BREEAM certification of excellence, it said in a statement.

“It has been a remarkable journey over the past 14+ years,” Logie Fitzwilliams, head of international business and global head of sales at Brown Advisory, said. “We have grown from a tiny sales operation to a much broader business, managing equity, fixed income and ESG strategies for institutional clients and financial intermediaries, as well as bespoke discretionary portfolios for private clients and charities. One of the most important parts of our culture is collaboration and the new office enables us to focus on that.”

The firm credits its business expansion to the success of its US sustainable growth strategy, its private client and strategy and global equity investment teams, and its global sustainable total return bond fund launched last month. 

The group oversees more than $140 billion in client assets.
