Name one distinctive feature of Mies van der Rohe’s architectural style.

Mies van der Rohe is renowned for his pioneering use of glass and steel, which became hallmarks of his architectural style. This distinctive feature embodies his modernist philosophy that emphasized minimalism and structural honesty. The extensive use of glass allows for transparency and a seamless connection between the interior and exterior, fostering an open and airy environment. Steel, on the other hand, provides the strength necessary for creating large, open spaces and enables innovative structural designs that were previously unachievable. Together, these materials exemplify Mies' famous adage, "less is more," showcasing simplicity and functionality while maintaining an aesthetic elegance. This approach has had a profound influence on modern architecture, making it a recognized characteristic of his work.
