Who Is This Diploma For?
This Interior Design Diploma Online may be a good fit if you want a structured introduction to the creative and practical side of interior design without committing to classroom-based study. It can also suit learners who already have an interest in interiors and want a broader course than an introductory short programme.
- Beginners exploring interior design for the first time.

How This Level 5 Diploma Differs from Other Interior Design Courses
eLearning College offers three interior design study options with different levels of depth. Choosing the right course depends on how much detail you want and where you are starting from.
If you want a shorter starting point, you can begin with our introductory Interior Design Short Course. If you prefer an intermediate option, compare the Level 3 Certificate in Interior Design. The Level 5 diploma remains the broadest of the three published interior design programmes.
Flexible Online Study
The course is delivered online and has an ongoing start date. There are no entry requirements, so you can begin without a formal prerequisite. The course duration is three months, while the online format gives you the practical convenience of studying from home around work, family and other responsibilities.
If you are new to online learning, our guide to eLearning can help you understand how flexible digital study works and what to expect from self-paced learning.
Assessment and Progression
The course uses end-of-unit assessments. You work through the supplied learning materials and complete each assessment as you progress. After successfully completing the course in full, you can choose whether to request an optional certificate or diploma as evidence of completion.
Interior Design as a Practical Skill
Interior design combines creative judgement with practical planning. A strong scheme needs to look considered, but it also needs to support how a space is used. That means thinking about movement, proportion, lighting, colour, surface finishes and the relationship between furniture and available space rather than treating decoration as a separate exercise.
For a closer look at one of these core areas, explore our guide to space planning in interior design, which explains how layout, circulation and furniture placement affect the usability of a room.
Thinking About a Career in Interior Design?
A diploma can help you build knowledge, but it does not by itself guarantee employment or professional recognition. Requirements vary by employer, location and type of design work. If you are exploring the profession, our guide to interior designer jobs and career pathways provides a broader overview of typical responsibilities, work environments and common routes into the field.

COURSE CONTENT
Begin by exploring interior design as a profession and the role of the professional interior designer. This unit establishes the context for the course by considering what interior designers do, the different aspects of the profession and the main factors that need to be considered when developing a design scheme.
This unit focuses on the principles that help an interior feel coherent and visually balanced. You will examine unity, balance, proportion, scale, rhythm and emphasis, and consider how these principles influence decisions about space, layout and the overall character of an interior.
Explore the individual elements that bring an interior scheme together. The learning outcomes for this stage include colour schemes and lighting, together with the contribution of walls, ceilings and flooring. The emphasis is on understanding how these elements influence atmosphere, usability and visual consistency.
Develop your understanding of space and how a room functions in practice. This unit considers orientation, circulation, inter-zoning and the arrangement of fixtures and furniture, helping you think more carefully about how people move through and use an interior.
Follow the development of an interior design project from early analysis through the communication of ideas. The learning outcomes include design analysis, drawing skills and presentation skills, giving you a clearer picture of how concepts are developed, refined and presented.
The final unit introduces the commercial side of interior design. You will consider the advantages and disadvantages of starting an interior design business and explore the importance of developing a professional, competitive portfolio that presents your skills and design thinking clearly.
