A lattice screen fading in the white walls by day, at night a screen of light and shadows is presented on the façade of Casa la Blanca. One of the typical Mexican lattices, widely used for decades in the State of Colima, within its cities and on the coast to protect itself from the intense sub-humid warm climate and its strong climatic changes. It is used as a skin to protect the house, giving privacy, security, effects of light and shadow indoors and outdoors.
