Office of Metropolitan Architecture
Rem Koolhaas' Office of Metropolitan Architecture (OMA) is on a shortlist of four to replace the rundown 1970s Forum des Halles in Paris. The much-criticised building will be demolished to make way for an attraction that aims to 'rival the Eiffel Tower, Pompidou Centre and the Louvre'. OMA proposes 21 coloured pyramids dotted over the site with a series of underground developments. The practice is up against French-based David Mangin and Jean Nouvel, and this year's Serpentine pavilion architect, MVRDV. A winner will be announced at the end of May and work is scheduled to start in 2007.
