Welcome to the advanced world of interior design. This foundational module is part of the Diploma of Interior Design (MSF50222) at IDI, an internationally accredited program aligned with the Australian Qualifications Framework (AQF) Level 5 and regulated by the Australian Skills Quality Authority (ASQA). As a Diploma student, you will gain not only professional recognition but also access to exclusive resources, including the Darren Palmer Video Masterseries, SketchUp training, and personalised guidance from highly specialised tutors.

Module 1 is designed to help you develop a professional understanding of the visual language of interiors. You will explore the elements and principles of interior design in a structured and analytical way, learning to interpret colour, texture, light, pattern, and space with confidence. This module lays the groundwork for creating sophisticated and functional spaces that meet both client needs and industry standards.

Through interactive exercises, guided analysis, and practical applications, you will start to refine your own designer’s eye. You’ll learn to assess the mood, style, and atmosphere of interiors, understand the rationale behind design decisions, and begin to articulate your observations in a professional context. By the end of this module, you will not only recognise quality design but also understand the reasoning behind it, preparing you to create interior spaces that are innovative, functional, and aesthetically engaging.
