Interior Designer

An Interior Designer plans, designs, and coordinates the interior environments of residential, commercial, hospitality, healthcare, and institutional spaces to be functional, safe, aesthetically pleasing, and compliant with building codes and accessibility standards. Unlike interior decorators (who focus on surface finishes, furnishings, and decorative elements), interior designers address space planning, lighting, materials, acoustics, ergonomics, building codes, fire safety, and accessibility—they are trained professionals who may work with architects and engineers. This role exists across residential design (private homes, apartments, luxury residences), commercial design (offices, retail stores, restaurants, hotels, lobbies), hospitality design (hotels, resorts, restaurants, bars, clubs), healthcare design (hospitals, clinics, dental offices, assisted living, senior living), institutional design (schools, universities, museums, libraries, government buildings), set design for film and television, exhibition and trade show design, product design for furniture, lighting, and textiles, and design consultancy. Interior designers work at interior design firms, architecture firms (in-house interior design department), real estate development companies, hospitality groups, corporate facilities departments, healthcare systems, retail brands, furniture showrooms, or as freelance/self-employed (most common for residential designers). Titles vary: Interior Designer, Interior Architect, Commercial Interior Designer, Residential Interior Designer, Hospitality Designer, Healthcare Designer, Set Designer.
