"Less is more" means "less is more". The phrase originally came from an 1855 poem by English poet Robert Browning.

Mies van der Rohe, a German architect, is one of the most famous modernist architects. He established a clear modernist architectural style, put forward the position and principle of "Less is more" in 1947, and advocated a new concept of flowing space in terms of processing techniques.

"Less is more" embodies the rigor and rationality of the Germans. "Less" is not blank but streamlined, and "more" is not crowded but perfect. Mies's architectural art relies on structure but is not limited by structure. It arises from structure and in turn requires the careful crafting of structure. "Less is more", Mies said to his students, "I hope you can understand that architecture has nothing to do with the creation of form."

The German Pavilion in Barcelona is an example of this, in which Germany used Among the exhibits that participated in the 1929 World's Fair, there was absolutely no superfluous thing added to the building, no messy decorations, no changes out of thin air, and no strange-shaped furnishings. There is only the light and transparent building itself and the continuous circulation space inside and outside it.

Similar to this is the Seagram Building in New York built from 1954 to 1958. This skyscraper that seems to rise from the sky is undoubtedly one of the most exquisite buildings in New York. This exquisiteness does not come from the carved moldings inside and outside the building, but from its exquisite structural components, brown glass and simple interior space.
