Which feature of International Style architecture emphasizes open interiors?

The feature of International Style architecture that emphasizes open interiors is the generous use of glass. This design choice allows for extensive natural light to flood the interior spaces, creating a sense of openness and spaciousness. The large windows and glass facades are characteristic of this architectural style, promoting a seamless connection between the interior and exterior environments. This transparency is essential in fostering a feeling of continuity and flow within open floor plans, aligning with the International Style’s principles of simplicity and functionalism.

In contrast, large decorative doors and heavy stone walls would potentially create barriers and compartmentalization within a space, detracting from the idea of openness. Narrow hallways also conflict with the concept of open interiors, as they would constrain movement and limit spatial interaction. Thus, generous use of glass stands out as the crucial element that enhances the sense of openness typical of International Style architecture.
