In the past, in a less densely populated urban context, houses and buildings were built with a direct connection to the street, with no need for walls and front fences. Over time, the urban fabric was transformed, and the division between public and private spaces became increasingly evident and — under the argument of public safety — necessary. Although this division occurs in different ways in Brazilian cities, in general, walls, fences and railings are used on the facades, creating a transitional space between the building and the street, transforming the relationship between them.
