ART OF CONSTRUCTION, STONE, AND FAÇADES

French built heritage is of major importance worldwide and to the general population, as evidenced by the profound emotion sparked by the Notre-Dame de Paris fire in April 2019. Mankind is viscerally attached to stone and its preservation. It connects us not only to our land, to the earth, but to our history—to History with a capital H. For centuries, precise rules have governed the construction, maintenance, and renovation of Historic Monuments. These rules define the framework in which the French urban landscape is shaped and evolves. One can therefore speak of an art of building, of façades, and of decorative architectural elements. Evaluating the quality of constructions and authenticating them requires in-depth knowledge of stonework, paneling, methods throughout the centuries, and the habits and techniques of architects and builders. The experience of the expert in historic buildings allows for a precise assessment and evaluation of constituent elements and their possible transformations, the choice of materials used for their renovation and restoration, and the work necessary for consolidation and potential adaptation to other locations. Ultimately, this expertise determines the value of a property, its insurance, and also its repair or replacement in the event of a loss.
