3 Best Free Courses On Interior Design online (2023)

What use is your home if it doesn’t reflect your personality?

Interior design works towards creating inviting, practical beautiful spaces that enhance our experiences and our living spaces.

However, design is far more complex than just having a knack for practical knowledge that what should go where.

Of course, having a natural instinct for design is a great start, but you’ll need to put yourself through some far more complex training if you want to make a career out of it.

If you’re ready to turn your natural instincts for design into a career, why not test the water first with these free courses on interior design?

What Is Interior Design?

Before we give you access to plenty of fun, comprehensive resources to kickstart your learning journey with, let’s go back to basics.

What is interior design? If you’re here, this may seem like a pretty basic question.

However, many people don’t quite understand the complexity of the job, and even you may be underestimating the exact skills and requirements needed to become an interior designer.

In simple terms, interior designers design and create functional and attractive indoor spaces for their clients using a broad range of skills and materials.

However, the reality is far more complex. This role is pretty multidimensional and complex.

Your job will involve a series of responsibilities, starting off with providing accurate, reliable advice in either (or both) commercial and residential sectors.

You’ll be able to provide people with thorough final design concepts, proposals for space planning, material specifications, and detailed coordinates to guide a project through to completion.

Some of the more specific duties carried out by interior designers can include:

  • Creating 2D or 3D design plans
  • Supplying timelines and product schedules
  • Be the point of contact for any contractors and constructors on site
  • Consulting with architects and trade specialists to get the job done
  • Providing advice on how to layout the interior, maximize space, and propose any relevant configurations.

As an interior designer, your main goal will be to create a functional, accessible environment that’s safe and practical.

This free course is aimed at anyone looking to break into the world of interior design.

You don’t need any prior knowledge to get started, but even if you are already experienced, you may still learn a thing or two.

Interior Design Courses: What To Consider?

Although there are more free interior design courses popping up all the time, we’ll be honest – at the minute, the options are limited.

The main issue is with quality – not all interior design courses are of a consistently high standard, and it can be challenging to find an interior design skills course that is as comprehensive as paid courses.

However, there are still several options to choose from, with the list above including some of our personal favorites.
