When planning a home or commercial space, many people get confused between architecture and interior design. While both professions are closely related and work together on projects, they serve very different purposes.
In this detailed guide, we explain the difference between architecture and interior design, roles, responsibilities, education requirements, costs, and which professional you should hire.
What is Architecture?
Architecture focuses on the design and construction of buildings. Architects are responsible for planning the structure, layout, safety, and functionality of a building.
An architect ensures:
- Structural stability
- Building compliance with local laws
- Space planning
- External design and elevation
- Sustainability and ventilation
- Foundation and load-bearing systems
Architecture deals with the entire building structure, from foundation to roof.
What is Interior Design?
Interior design focuses on enhancing the interior spaces of a building. It deals with aesthetics, comfort, functionality, and user experience inside the structure.
Interior designers handle:
- Furniture layout
- Lighting design
- Color schemes
- False ceiling design
- Flooring materials
- Decorative elements
- Storage planning
Interior design improves how a space looks and feels.
