In a context of a consolidated historical neighborhood we are faced with a defined typology of dwellings between party walls and patios shared by neighbouring plots. Since volumetry is already determined the main challenge is to make the most of the resulting surface.

The layout of the façade is defined by the regulation, which requires employing the conventional regulated wall openings composition. In order to comply with this restriction we used a modern technique of ventilated openable façade made out of perforated corten steel that mimics the traditional arrangement of the openings. Besides, the corten steel skin creates a double bio-climatic façade that takes advantage of the sun in the winter for passive heating retention and protects from solar radiation in the summer, like an Arab jalousie. This strategy leads to a contemporary mimesis in a historical environment, which also allows for updates to the historical typology of our times.
