The turn T1 is currently a Gratte-ciel of offices in construction by Bouygues in the district of business of Defense, in France (precisely with Courbevoie, in the district of the Faubourg of the Arch).

Tower T1 should be delivered for 2008; it will have a 185 m height, which will make of it the second round highest of Defense (after the Total Tour).

Conceived by the cabinet of architects Valode and Pistre, it will have the shape of a sheet folded into two, resembling an inflated sail. The southern frontage of the tower will be strictly vertical (towards Defense), whereas northern side the frontage goes down gradually towards Courbevoie thus ensuring a transition with the low city.
