The Picard nursery is nestled against two gable walls. The urban plot is cold and difficult ; hence the need to create a new inner space wrapped around a central patio and a protective outdoor space. The building is covered with a zinc caparison - the iconic material of Parisian roofs – and looks like a pirate boat, or a doll house. Colors are used to give more rhythm to the different spaces, to create convergence lines and to catch some of the sunrays. The two-storey nursery is a singular and unusual object with a complex geometry and a playful arrangement of materials : the zinc skin covering the roof and façades creates a feeling of protection, the colored metal sheets give life to the façades and the tiny landscaped outdoor spaces bring more natural light into interior spaces.
