Glass interior design involves incorporating glass elements into the design of a space to create a modern, sleek, and visually appealing environment. Here are some ways to incorporate glass into interior design. Use glass walls or partitions to divide spaces while maintaining an open feel. This allows natural light to flow through the space, creating a sense of openness and connection between different areas. Replace traditional doors with glass doors to allow light to pass through and visually expand the space. Frosted or tinted glass can be used for privacy where needed.
