In 1967, at the end of a career spanning more than six decades, which included the design of Seagram Building in New York, The Lake Shore Drive Apartment Buildings in Chicago, and The Neue National Galerie in Berlin, architect Mies van der Rohe (1886-1969) designed a simple gas station near Montreal. The story of that gas station serves as the point of departure for REGULAR OR SUPER, which examines Mies' entire body of work (more than 70 buildings) and sparse style that reflects his motto : "Less is More"

Mies is undoubtedly one of the biggest architect in 20th century and my favorite. 
He designed Timeless building to amazingly well known chair... his work still exist today, his chair always used by nowadays designer in the interior,.. and it does not look old. 

even most of so called "star-architect" nowadays can not match his level of design..
Less is More is the most famous quotes in the world.. motto and way of life.
and it is Chrystal clear in his work.

 

Well,... I'm not going to talk about Mies' history and work further than this ( simply this is not the place really) but The movie tells it cleverly. You will understand why Mies works are special, Why something so simple can be so attractive and timeless.. Why something very carefully designed does not look like it was designed at all (in ordinary people eyes),... and most importantly why Less is More..

"Less is More" IS the very foundation of "Design not Decorative" which is I believe it is the core of design.
