Decor choices can significantly enhance the feeling of space. Large mirrors, when positioned correctly, reflect light and views, giving the illusion of a larger room. Use transparent materials like glass or lucite for tables or desks to keep spaces open and uncluttered, and consider light fabrics and textures that add depth without bulk. Additionally, opting for streamlined furniture with exposed legs enhances openness, as it allows more visible floor space, tricking the eye into perceiving a larger area.
