Rogers Stirk Harbour & Partners experienced a meteoric rise in the 2006 financial year, with before-tax profits of nearly £1.3 million. This is compared to pre-tax losses of £708,959 in 2005.
The practice also saw its turnover soar by £6.9 million, from £16 million in 2005 to £22.9 million in 2006.
The fiscal results follow a run of good news for the practice, which last month changed its name from Richard Rogers & Partners.
Rogers picked up the Stirling Prize last October with his Barajas Airport terminal in Madrid, and also saw his Welsh Assembly shortlisted for the award.
The septuagenarian then scooped one of architecture's most coveted awards, the Pritzker Prize, which is viewed as the 'Nobel Prize of architecture'.
And the practice is unlikely to look back: it was recently unveiled as lead architect for the transformation of the Chelsea Barracks - one of the country's most valuable pieces of real estate - and earlier this month it unveiled its first completed tranche of the Government's £60,000 house scheme, called Homes of the Future.by Richard Vaughan
