Every time I wander through big cities my look often goes towards buildings with simple architecture, but with a strong relationship with the place where it is implanted, therefore generating a great result.

The term minimalism is used to describe a trend in design and architecture, wherein the subject is reduced to its necessary elements. Minimalist architectural designers focus on elegant lighting, and the void spaces left by the removal of three-dimensional shapes in architectural design. 

There are observers who describe the emergence of minimalism as a response to the brashness and chaos of urban life. In Japan, for example, minimalist architecture began to gain traction in the 1980s when its cities experienced rapid expansion and a booming population. The design was considered an antidote to the "overpowering presence of traffic, advertising, jumbled building scales, and imposing roadways." The chaotic environment was not only driven by urbanization, industrialization, and technology but also the Japanese experience of constantly having demolished structures on account of the destruction wrought by World War II and the earthquakes, including the calamities it entails such as a fire.
