Professional interior designers will usually follow a set of informal “rules”, based on specific interior design principles and elements. These interior design elements include space, line, forms, light, colour, texture and pattern; and keeping them balanced is the key to creating an aesthetically pleasing interior.

You will need to budget INR 20,000 – 50,000 approximately for a living room with basic interiors and furniture. And for a premium one it can range between INR 75,000 – 1,00,000 Lakh.

Interior design is the art and science of understanding people's behavior to create functional spaces within a building, while interior decorating is the furnishing or adorning of a space with decorative elements to achieve a certain aesthetic. In short, interior designers may decorate, but decorators do not design.
