Interior designers plan and design building interiors. This might include; offices, hotels, restaurants, retail spaces, hospitality, healthcare, theatre set and exhibition design, domestic interiors, and so on. It may involve interiors for new buildings, or the redevelopment of existing spaces.
Interior design is not a clearly defined practice. It covers a wide range of activities and includes elements of the creative arts and of architecture. The profession is a relatively new one, and the title is not regulated, that is, anyone can call themselves an interior designer.
Interior design is sometimes perceived to be a matter of interior decoration, but in fact, it is a complex subject that often involves working alongside other professionals such as architects and engineers as part of a larger project, and requires detailed knowledge of:
- Design styles.
- Spatial design.
- How people are affected by their environments.
- Construction and materials.
- Regulations and approvals.
- Procurement and project management.
- Technical matters such as acoustics and lighting, and increasingly, technologies such as audio visual equipment and ITC.
- The role of other consultants.
Many interior designers work on a freelance basis, others are employed by consultancies, or work through agencies. They may also be employed directly by repeat developers such as retailers or by architectural practices or multi-discipline design practices.
Qualifications may include art and design-based BTECs and HNDs, or degrees in interior design, 3D design, spatial design, fine art, architecture or interior architecture. Interior designers may also become members of an institution such as the British Institute of Interior Design. Some interior designers may specialise in the design of a particular type of space.
