In a mythical and historically artistic Parisian street, between boulevards Raspail, Montparnasse and Vavin, a workshop in a freestone building. Deployed on two levels with beautiful volumes under a mixed wood-steel frame and large bay windows overlooking a private courtyard with views of a Japanese garden, the workshop consists on the ground floor of an open space - space covered by a skylight. Upstairs, a fully glazed closed space with pivoting windows allowing connections with the patio and the open-space. Possibility of three or four bedrooms with two bathrooms with a plan that allows multiple possibilities. Quality renovation keeping its original character. This unique place, having belonged to the great couturier Yves Saint Laurent, is willingly intended for a residential housing project.
