 The average house in the 14th century had a ground floor, two floors of residential space, and another smaller residential space under the roof on the third floor, but there were also a large number of houses with four floors on the Rue Saint-Denis, the Rue Saint-Honoré and other streets, and a five-story house is recorded on the Rue des Poulies.Given that the area of Paris within the city walls in 1328 was 439 hectares, and the population was two hundred thousand, many of those counted probably lived outside the city walls.It remained very high in the heart of the city, except during times of war and the plague, until the reconstruction by Napoleon III and Haussmann in the mid-19th century.
