Residential construction is the fundamental 'basic' component of the urban scene. The elementary cells have an average net span of 6x6m, but there are also some 7-8x4-5m rectangular shape cells.
The basic typology was the house with one or two overlapping cells; the upper space was accessed through an external staircase extended on the front, called the profferlo. The semi-basement level was used as a cellar and for storing firewood. Today, most of the profferli have been demolished or enclosed in the interior of the dwelling unit, through the partial or total demolition of the facade of the building, and the construction of a new external wall.
