About the Interior Design Course

A house becomes a home with your skilled touch and creative vision. Our Interior Design course gives you all the training and skills you need to create beautiful and comfortable homes.

The Interior Design Diploma Course is delivered online, consisting of 12 comprehensive modules and 12 corresponding interactive assignments. The normal time required to complete the course is 24 weeks, however you can take up to 12 months to finish, if required.

The modules are designed to be read sequentially and will help build your knowledge to enable you to design a residential space.

There are exercises at the end of each module which will require you to participate in the design experience. It is through participation and interaction that you will learn to feel confident and find your creative voice. The exercises are designed to help you build your first professional portfolio.

Each student will be given the same residential renovation task that will require them to upload new floor and lighting plans, suggest furnishings, fabrics, window treatments, lighting, upholstery and accessories, explore decoration and various design styles, provide colour schemes, upload mood boards, write quotations, prepare newspaper ads, write a scope of works for your contractors, provide a preliminary costing for your clients, etc.

As this is an online course, we understand that some of our students do not have access to real life renovations or clients, so each project completed throughout our course will be hypothetical.

Experience the transformation as your thoughts and opinions evolve while gaining more knowledge and skills. Enjoy the process of gaining skills that will enable you to communicate your untapped creative potential.

How to study online?

All the learning is done online in that when you enrol you receive a username and password, which enables you to log onto our secure student site. From there you can download your first module, which you could liken to your textbook as it contains all the information you will need to complete assignment one. Each module is approximately 80 pages in length and is full of detailed technical information delivered in a friendly, conversational manner that is easy to understand. The concepts are further explained by way of diagrams, images and examples.

Once you have completed your assignment (some are just theoretical, but the majority of assignments combine both theory and fun practical tasks) you then upload it onto our site for your tutor to mark. The tutors will give you a grade (out of 10) and a comprehensive evaluation of your work and ideas and help nurture and improve your skills each step of the way.

What makes The Interior Design Institute so unique is that throughout our course you have access to the safety net and guidance of the team here at Student Support, who you can contact 24/7. It is not simply a case of giving you a textbook and off you go - far from it.

You also have direct contact with your personal tutor who guides you closely through each step of the course, offering personalised and specific constructive criticism on your submitted work. If you ever have any questions in relation to your course or assignments, all you need to do is send your tutor a quick message and they will reply with an answer as soon as they can.

With this close tutor mentorship, you will feel like your tutor is in the same room as you, and all this can be achieved from the comfort of your own home. That is the beauty of our course, you can study when you like and at your own pace.

The tutors who work for us are not just teachers, but the best working professionals in their field. By drawing on their knowledge you will gain an edge that will help you realise your true potential.

We have a Facebook Group that we have exclusively designed for our students.

On successful completion of the Interior Design Course you will be awarded a Diploma in Interior Design. You will have the skills and knowledge required to become an Interior Designer either as a full or part time career, as a profitable sideline or just as an exciting new hobby.

This wonderfully fun course really opened my creative side. I now see design elements wherever I go that I would have never even noticed before. It has helped me blend my drafting, technical side with the creative side that I had but wasn't using to its potential.
