Starchitect

Starchitect is a portmanteau used to describe architects whose celebrity and critical acclaim have transformed them into idols of the architecture world and may even have given them some degree of fame amongst the general public. Celebrity status is generally associated with avant-gardist novelty. Developers around the world have proven eager to sign up "top talent" (i.e., starchitects) in hopes of convincing reluctant municipalities to approve large developments, of obtaining financing or of increasing the value of their buildings. A key characteristic is that the starchitecture is almost always "iconic" and highly visible within the site or context. As the status is dependent on current visibility in the media, fading media status implies that architects lose "starchitect" status—hence a list can be drawn up of former "starchitects".
