The search for outdoor spaces in dense city dwellings has become for some a necessity and for others a requirement to be fulfilled. In short, it is one of the most sought-after commissions that architects around the world receive on a daily basis. Beyond the fact that this phenomenon has been accentuated during the Covid-19 pandemic, since their origins, these expansion spaces have been conceived not only to increase the use of natural lighting and ventilation but also to promote the indoor-outdoor relationship, giving the possibility to accommodate various uses and functions even when square meters are scarce or when the connection with nature is glimpsed far over the horizon.
