London-based architect Hadid received a CBE. Hadid's work includes the modernist design of the National Museum of Contemporary Art, currently under construction in Rome.
RIBA member David Martin was also awarded an MBE. Martin worked as conservation officer at Glasgow council between 1979 and 1999.
Other architects honoured included John Spencely CBE and Stephen Gardiner OBE. Spencely is a former president of the Royal Incorporation of Architects in Scotland, and Gardiner was an architecture critic at The Observer.
Architects fared better than most of the industry, although Christine Wood, president of the National Federation of Builders Yorkshire Association, was awarded an MBE. Jonathan Harris, former president of the RICS, added a CBE to the OBE he already holds.
Judith Mayhew, the New Zealand-born chairman of the Corporation of London's planning and resources committee, was made a Dame Commander of the British Empire. Mayhew has worked with London mayor Ken Livingstone to ensure that the government gives the go-ahead to the 37-storey Heron Tower development in the City. The move is crucial to the implementation of Livingstone's tall buildings policy.
