Grimshaw made pre-tax profits of £7.9 million in the year to March 2018, up a quarter on the previous year fuelled by significant growth in its overseas workloads
The firm’s worldwide financial results show an £11.6 million rise in turnover to £70.9 million.
The firm attributed the strong performance partly to its expanding presence in Australia, where it said profits were now on a par with London and New York.
Chief financial officer Neil Boyde said: ‘After another year of significant growth we have doubled our size in the last three years, improved profitability and established a genuinely global presence.
‘The focus now is on capitalising on this success to consolidate our strength as a business alongside architectural excellence.’
Grimshaw’s redevelopment of London Bridge Station in London opened to the public in early 2018.
Other completed projects during the year included Vaughan Metropolitan Centre Station in Toronto and 333 George Street, a commercial scheme Sydney, where the practice has taken space.
Grimshaw was selected for several major international transport projects including the masterplan revisioning of New York’s John F Kennedy International Airport, the new Terminal One for Newark Liberty International Airport, as well as major HS2 station works at London Euston and Birmingham Curzon Street stations.
The year also saw the practice set up an office in Los Angeles and create new legal entities in France and Singapore.
