"Phare" (lighthouse) is a new 300 metre (almost as high as Eiffel) tower to be built in La Defence to help Paris compete with other thriving business centres with iconic buildings like London's Swiss Re building, knicknamed "the Gherkin" . They don't like towers much in Paris- the Eiffel tower was initially described by the author Guy de Maupassant as "an odious tower of extreme bad taste". Mayne beat out the likes of Norman Foster and Rem Koolhaas to win the competition. "There's a fluidity, a sensuousness, a softness to the form as it reaches to the sky," he said, describing the asymmetric twist of the building, which swells out over an elevated lobby in the lower portion before tapering off to a thicket of wind turbines on the roof. Mayne says it will be "a prototype for a green building" with a wind farm generating its own heating and cooling for five months of the year and a movable "double skin" to cut the heat from direct sunlight through the windows. ::the Scotsman image from ::Marvellous Architectures more below the fold.
