Wilkinson Eyre Architects' before-tax profits have rocketed by more than 400 per cent for the year between March 2006 and 2007.
The double Stirling Prize-winning firm has recorded before-tax profits of £3.15 million, up by more than £2.5 million from the previous year.
It has been an exceptionally good year for the practice, which has seen its turnover soar from £997,000 in 2006 to £11.4 million in 2007.
Projects such as the much-anticipated Victoria transport interchange in central London, and the vast Southgate transport regeneration scheme in Bath will have helped with the firm's impressive results.
Wilkinson Eyre was also named this week among the ten shortlisted firms vying for two of the temporary venues for the 2012 Olympic Games.
Other prominent projects include the Singapore Gardens scheme, and it is also proposing a 'foggy' parkland on New York's Governor's Island.
