The Flower Tower was completed in 2004.Christian de Portzamparc, architect in charge of the urban regeneration zone of Hauts Malesherbes, had given us a carte blanche.The tower is the vertical continuation of an adjacent park. Its giant flower pots, hanging from the balconies, were inspired by Parisian window planters that can be in themselves botanical treasures. These façade elements were one of the first applications of Ductal (by Lafarge). The social housing is freed of all bearing walls. The inhabitants enjoy the rustling of bamboo and a light filtered by the foliage. The elevator is on the façade and, glazed on both sides, it allows light to penetrate into the common areas. On the ground floor, it opens to the outside, transforming the exterior into a hall.The Flower Tower embodies the expression of desire for nature in the city.
