Student Success Stories
Hear what our amazing students have to say about how they have succeeded within the industry once completing their Professional Interior Design Diploma with the National Design Academy.
I chose the National Design Academy because it offered the perfect blend of professional flexibility and academic depth. I completed my course in early October and I'm now expanding my professional network as I grow Fabian Interiors — a brand dedicated to creating timeless, nature-inspired interiors.
With the course being online, it was really convenient, as I could fit the course around my children and family life..... Since completing my Diploma last year, I set up my own online furniture shop and this year I have started an interior design service in and around Norfolk.
I enjoyed the course and it was ideal for my needs of working during the day and studying in the evenings and on the weekends. I have slowly incorporated my new skillset into my decorating business. I now have a client that is ready for a new dining room design. I cannot wait to start this journey into an industry I’m very passionate about!
The reason why I decided to study interior design with the National Design Academy was to learn the professional skills so I could take up projects for clients, not just friends and family. After I finished my course I started hiring to help me grow my existing business, Kad Design Studio. I now have a team of an Architect, Interior Designer and a Site Engineer.
I found the course to be very good if you want to kick-start your career in interior design. The VLS is easy to use and navigate around, which is helpful when studying fully remote. I’m continuing my studies with the National Design Academy onto the online BA (Hons) Interior Design Degree, so I can shape my future for a better one.
I studied the Online Fast-Track course in between working and caring for my toddler. It was challenging, but I loved the course so much, I was willing to fit it all in! Since finishing the course, I have launched my Interior Design services to my small business. I’m super excited for the journey and I’m looking forward for things to come.
I discovered the National Design Academy and the flexible study options. Now that was an idea! I could really fit the Interior Design studies around my work schedule! After finishing my course, my current plans are to use the knowledge and skills I learned to transform family, and friend’s homes into beautiful and functional spaces that reflect their personality.
