The company saw turnover increase by 14 per cent in the year ending April 2015 to £49.9m with profits of £3m compared to £1.4 in the previous year. Broadway Malyan employs 580 staff across design areas including public realm and landscape.
Managing director Gary Whittle said the practice had delivered superb work over the past year, including award-winning design and a number of master-planning projects. The current financial year also has a healthy pipeline of work, he added.
"While the company is headquartered in the UK and boasts a strong regional network, the past year has seen us grow our international presence with projects now being undertaken in 37 countries and turnover from these now amounts to 60 per cent of the company's overall revenue.
"The strength of our international studios and the quality of instructions reflects a growing understanding of these markets and justifies our strategy of retaining and growing our operations during the difficult economic conditions of the past few years.
"Looking forward we are investing across the practice while continuing to recruit key personal to help us achieve the long term strategic aims of the business."
