Interior designer Sanjay B Navgire showcases residential and commercial spaces

Interior design as a discipline emerged from a simple human need: to make the spaces we inhabit both functional and reflective of who we are. Unlike architecture, which concerns itself primarily with structural systems and building envelope, interior design operates within those boundaries to shape how people actually experience a room. It's about understanding flow, proportion, material qualities, and the psychological weight of color and form. The profession grew distinctly in the twentieth century as homes and commercial buildings became more complex, and as the relationship between people and their environments became understood as something requiring intentional thought rather than accidental accumulation. The practice separates itself from decoration, which is often about surface embellishment, through its engagement with spatial planning. An interior designer considers how light moves through a space at different times of day, how materials wear and age, whether a hallway invites movement or discourages it, how the eye travels from one plane to another. This requires both analytical thinking about dimensions and sightlines, and intuitive understanding of human behavior and comfort. The work sits at the intersection of problem solving and aesthetic vision, where every choice about a wall surface, a furniture arrangement, or a lighting fixture carries both practical consequence and emotional resonance. Residential and commercial projects present distinctly different design challenges because they serve different purposes and accommodate different rhythms of use. In residential work, a designer shapes daily life: how a kitchen encourages gathering or solitude, how a bedroom feels restful, how public and private zones within a home establish privacy while maintaining openness. Commercial spaces operate under different constraints. They must withstand higher traffic, serve multiple users with different needs, communicate a brand or function instantly, and endure wear patterns that would be unrealistic in a home. The same principles of proportion and materiality apply, but the stakes and performance requirements shift considerably. The material choices in interior design carry both practical and expressive weight. Surfaces must be selected not only for their visual appearance but for how they perform over time. Wood darkens and develops patina; concrete develops hairline cracks that become character; fabrics fade and show wear in patterns that reflect use. A thoughtful designer considers these trajectories, sometimes embracing them as part of the honest aging of a space, sometimes specifying materials specifically for their durability and resistance to visible change. The selection of finishes, textiles, and furnishings becomes a form of storytelling about what a space values and what it expects from those who inhabit it. The relationship between function and form in interior design has roots in twentieth century modernism, which taught that
