What an Interior Designer Does and How to Become One

Who is the Interior Designer?
The interior designer is one of the most sought-after creative careers in the world. With a mix of craftmanship and functionality, the interior designer reimagines both public and private spaces, envisioning how we will live and work in the future. More than just an interior decorator, an interior designer shapes experiences with spaces, colors, materials, lighting, and furniture.
In today’s design-driven world - spanning everything from fashion and luxury to architecture and product design - interior designers play a central role. They are increasingly influential in shaping the future of homes, workplaces, and hospitality environments. With styles ranging from Scandinavian interior design to industrial and maximalist interior design, they are at the heart of cultural trends and lifestyle evolution.
What does the Interior Designer do?
According to the interior designer job description, the role involves both creativity and technical skills. An interior designer works closely with clients to create well-functioning, aesthetically pleasing spaces. From room design in private homes to corporate environments and commercial interiors like restaurants or hotels, interior designers manage the complete design process, from initial concept to its final realization, while dealing with procedures and technical regulations.
Unlike a traditional interior decorator, who focuses mainly on visuals, a home interior designer ensures that every element in a space works in harmony, enhancing both comfort and usability. The home interior designers deal with the client’s requirements, research trends and materials, create digital and physical mood boards, and often use interior design software - or even AI interior design platforms - for digital rendering. Today’s designers can also work remotely as virtual interior designers, offering consultations and complete project oversight online. Their designs can range from luxury interior design spaces to sustainable, eco-friendly, and ethical interiors which meet modern environmental standards. The cost of an interior designer may vary based on professional experience and academic background, but the value they bring to a project often far outweighs the expense.
Competences of the Interior Designer
Professional interior designers combine artistic talent with technical knowledge and human insight. To succeed in the industry, a certified interior designer must have:
- A deep understanding of interior design styles
- Fluency in using interior design software
- Knowledge of space planning, ergonomics, lighting, and materials
- Creativity, adaptability, and a collaborative spirit
- Awareness of trends like Scandinavian, industrial, or maximalist interior design
- Familiarity with sustainable practices and eco-friendly solutions
Strong communication skills are also essential, as designers frequently liaise with clients, architects, engineers, and contractors. The profession also demands versatility - working on projects that range from personal room designs to large - scale hospitality environments.
