Holistic Interior Design Advanced Diploma

Ad. Holistic Interiors

This study course is suitable for on-going professional development and equivalent to a post-graduate Diploma for practicing designers and professionals working in associated holistic and healthcare fields.

Holistic Interior design is a fast growing area of architecture and interior design that offers a more sensitive, holistic, caring and environmentally friendly approach giving Holistic design professionals the edge in a very competitive market.

Interior Design training has for some time lagged behind current trends, so this course reflects the shift of emphasis that has taken place over the last decade. This advanced Holistic Interior Design professional Diploma course addresses a need for designers and decorators to take a more environmentally responsible and humanistic approach to interior spaces. This course extends your knowledge base and offers you new skills that allows you to create harmonious homes and work spaces that are eco-friendly but also beautiful and nurturing to the people who use them. Our course is updated regularly and the ideas can be applied to any style of building or interior, so you can adapt the material to grow your business.

Practicing designers will find this course allows them to use their talents in a new way and to offer their clients a more personalised service. We support our graduates by giving them one year free membership of HDI that is good to add to your CV, and we have a referral system too. There are 16 Lessons in this course. Lessons are delivered in email fully colour illustrated PDF documents, with web-links to further useful information and practical videos. This advanced level focuses on business development rather than starting up, and it is assessed to a higher level than the Diploma option, and students are expected to have previous design and drawing skills.
