Frequently Asked Questions (FAQs)

How long do I have to complete the course?

The course is designed to be self-paced. Normally, you would expect to be dedicating on average about 4-6 hours per week for 24 weeks. However, many students take up to one year to complete their studies because of family or work commitments.

How do I communicate with my tutor?

You can contact your tutor at any time through our secure student site, which you will gain access to once you enroll. Your tutor's role is to assess your assignments and provide you with feedback. They are also available to answer any questions you may have about the course.

Do I have to attend any classes?

No. The courses are completed online. This means there are no classes to attend. You can study in your own time and at your own pace.

Do I have to have a background in interior design?

No. The course is designed to allow for students who have had little or no experience in interior design.

What device is required?

Our course is compatible with both PC and Mac devices, and basic computer knowledge is required. You will need:

- Microsoft Office, Open Office, Google Docs or similar software
- Internet access
- Printer
- Scanner or digital camera

When can I start?

As the course is provided online, you have the flexibility to start when and where it suits you. If you enrolled today, for example, you could start straight away.

What materials are required?

We recommend students source the following items. These are completely optional:

Scale ruler / Standard ruler / Lead pencil / Eraser / Fine liner black pen 0.5mm / Blank paper to draw on or a visual diary / Tape measure

What if I need more time?

If you need more time, you can purchase one of our affordable extensions. We currently offer 3, 6 and 12 month extensions. Alternatively, you can purchase an Advanced Module, which will come with a 6 month extension.

Does the course include the Advanced Modules?

No. When you purchase our course, the Advanced Modules will not be included. Our Advanced Modules are short courses and are optional for those who wish to further their studies. They will be available to purchase for students who are enrolled in our course and have completed the first two modules. They are comprised of one module and one assignment and you are mentored by a specialist in the topic selected.

Can I purchase the Advanced Modules as a stand-alone course?

No. Unfortunately, we do not offer our Advanced Modules to the public. Only students enrolled in our course can purchase them.

What is the Darren Palmer Masterseries?

The Darren Palmer Masterseries is essentially a set of videos hosted by renowned designer and TV personality Darren Palmer, that accompany our course. When you are studying our course materials, we recommend that you also watch the videos by Darren, to gain more knowledge. These videos can be purchased when you join, or at any time during the course.

Do you mail any course notes or materials out?

Our courses are delivered online and all information is provided digitally. As soon as you enroll, you will gain access to our online student site. You can download the course materials as you proceed through each module. As the modules are provided in PDF format you can keep them for future reference and print if you wish. The only time we mail something out is when you successfully graduate our course.

Do the courses include Computer Aided Drawing (CAD) software?

Our course does not include any CAD software. We do, however, teach AutoCAD, ArchiCAD and SketchUp through our Advanced Modules. These can be purchased as you progress through the course.
