ABSTRACT
The regulations that control urban construction, while simultaneously limiting spontaneous constructive procedures, also contribute to the establishment of new ones. With this purpose, the Lisbon City Council introduced the 1864 regulations, expanded in 1869. These were valid until 1886 and replaced in 1930. These codes defined the volumetry of the buildings and also constructive elements that could interfere with street or sidewalk traffic. However, implementation of these regulations was not a linear process, with amendments emerging with the everyday construction practices and constructive techniques. This article analyzes the regulations related to the drainage of rainwater from building roofs to the ground; maximum height of new buildings and extensions of existing structures; constructive elements suspended above the street; modifications to the shape of doors and windows; and relations between the working site and the public space.
