Foster and Partners For anyone to poll 50 per cent in any survey is formidable. Foster and Partners has bettered even last year by 2 per cent, despite some adverse press criticism, such as the British Museum South Portico 'wrong stone' saga and the still-closed wobbly bridge. But to counter them there was the Great Glasshouse in Wales and, to come, the Swiss Re tower .
Allies and Morrison Architects Allies and Morrison, the RIBA's house architect, has had a leap of faith, winning less than 1 per cent last year. The practice is accruing work and expanding - wins include a £100 million office and broadcast centre for the BBC at White City, new visitor centre for Bristol Cathedral, £20 million Manchester mixed-use scheme, and housing at Highbury for Arsenal FC.
Michael Hopkins & Partners Michael Hopkins and Partners'stock has also risen. The practice's offices scheme at Portcullis House for MPs won an award from the Institution of Structural Engineers - but little other good publicity. Hopkins' Nottingham University Jubilee Campus fared far better, clinching the British Construction Industry Awards'main building prize.
Richard Rogers Partnership A phenomenally busy year for Lord Rogers of Riverside, with the publication of his Urban Task Force report and the Urban White Paper, as well as his appointment by London's new mayor Ken Livingstone to become 'city architect'. Rogers'popularity waned just a little, down from 11 per cent last year, but the practice's finances remain in fine fettle.
David Chipperfield Architects Admiration for David Chipperfield Architects dwindled, but the office is still busy, mostly abroad. Chipperfield's was one of four practices eventually selected for the British element of the Venice Biennale.
Meanwhile, the office won permission for its cemetery extension there, and won a competition for a 3,000m 2building in Leichtenstein.
Feilden Clegg Bradley Architects More plaudits this year for the practice noted primarily for its lowenergy buildings in a year in which it added 'Bradley' in honour of senior partner Keith ( on the right of the picture with Peter Clegg, centre, and CABE commissioner Richard Feilden, left).Key schemes: Marlborough House in Warminster, Wiltshire; and student space at Imperial, London.
Nightingale Associates Nightingale Associates, headed by the eponymous Mike (pictured), is a new entry to the top table, not even garnering 1 per cent last time.
Noted for healthcare, it has set up a health planning group headed by partner David Clarke. Last month it was celebrating: the PFI contract for its £50 million redesign of West Middlesex Hospital was signed.
