What is extended visually by using wide expanse of glass in interior design?

The use of a wide expanse of glass in interior design can visually extend the space by creating a sense of openness and transparency. This can make the room feel larger and more connected to the outdoors, allowing natural light to flood in and providing unobstructed views of the surrounding environment. Additionally, the use of glass can create a modern and sleek aesthetic, adding a touch of sophistication to the overall design.
