With blocks that are longer in length, narrow corridors provide the opportunity for cut throughs. These corridors feature small merchant spaces.
These narrow passageways serve as an access point but also enable the development of secondary merchant spaces. Oftentimes these passageways are narrow in width which translates to the size of the merchant space. These merchant spaces are formal in nature but also provide an opportunity for inclusive economic development by providing inexpensive space for rent. The narrowness enclosure makes it a design challenge.
In some cases, these spaces are open to the elements. In this design pattern, the secondary story provides enough space for natural ventilation to occur.
