Lesson 2 • Defining Interior Design as a Profession
Clarifies the distinction between interior design, interior decorating, and architecture. Sets professional boundaries students will apply throughout the course.
Lesson 3 • The Design Process Overview
Maps the full project lifecycle from initial brief to final installation. Students understand how each phase connects before studying each in depth.
Lesson 4 • Core Design Vocabulary
Introduces essential terminology used across all design disciplines. Accurate language enables precise communication with clients and collaborators.
Chapter 2HideHide detailsSee detailsElements and Principles of Design
Elements and Principles of Design
Lesson 1 • Compositional Principles
Explores balance, rhythm, emphasis, proportion, and harmony as tools for organising space. These principles transform individual elements into unified compositions.
Lesson 2 • Fundamental Design Elements
Covers line, shape, form, space, and texture as the raw components of any interior. Understanding elements precedes applying compositional principles.
Lesson 3 • Color Theory for Interiors
Teaches the colour wheel, colour relationships, and psychological impact of hue, value, and saturation. Colour decisions directly affect mood and spatial perception.
Lesson 4 • Applying Elements and Principles Together
Integrates elements and principles through analysis of real interior case studies. Students practise identifying and critiquing design decisions in existing spaces.
Chapter 3HideHide detailsSee detailsDesign Drawing and Visual Communication
Design Drawing and Visual Communication
Lesson 1 • Elevations, Sections, and Details
Produces interior elevations, cross-sections, and construction detail drawings. These views communicate vertical relationships and material transitions to contractors.
Lesson 2 • Freehand Sketching Techniques
Builds confidence in quick ideation sketches, perspective views, and annotated thumbnails. Freehand drawing accelerates concept exploration before formal drafting begins.
Lesson 3 • Introduction to Digital Drafting Tools
Introduces CAD and BIM software interfaces for producing precise interior drawings. Digital tools increase accuracy and enable rapid design iteration.
Lesson 4 • Technical Drawing Conventions
Covers orthographic projection, drawing scales, line weights, and title block standards. Technical accuracy ensures drawings are buildable and professionally credible.
Lesson 5 • Floor Plans and Reflected Ceiling Plans
Teaches construction of accurate floor plans and reflected ceiling plans with correct symbols. These drawings form the core of any interior design document set.
Chapter 4HideHide detailsSee detailsSpace Planning and Functional Layout
Space Planning and Functional Layout
Lesson 1 • Circulation and Traffic Flow
Analyses primary, secondary, and tertiary circulation paths within a space. Effective traffic flow prevents congestion and supports the intended use of each zone.
Lesson 2 • Reading and Interpreting Floor Plans
Teaches how to read architectural drawings, symbols, and scale conventions. Plan literacy is required before students can create or modify layouts.
Lesson 3 • Understanding Space and Human Scale
Introduces anthropometrics, ergonomics, and clearance standards that govern liveable space. Accurate human-scale data is the foundation of every layout decision.
Lesson 4 • Space Planning for Different Room Types
Applies planning principles to living rooms, kitchens, bedrooms, and open-plan offices. Context-specific constraints reinforce adaptable planning skills.
Lesson 5 • Furniture Arrangement Strategies
Covers conversation groupings, focal point orientation, and multi-use layouts. Students apply arrangement strategies to diverse room types and client needs.
Chapter 5HideHide detailsSee detailsMaterials, Finishes, and Specifications
Materials, Finishes, and Specifications
Lesson 1 • Flooring Materials and Selection
Compares hardwood, tile, carpet, vinyl, and concrete flooring across durability, cost, and aesthetics. Material choice must match the functional demands of each space.
Lesson 2 • Writing Material Specifications
Teaches how to compile accurate material schedules, cut sheets, and finish boards. Precise specifications prevent costly errors during procurement and installation.
Lesson 3 • Cabinetry, Millwork, and Hardware
Details cabinet construction methods, wood species, hardware types, and finish options. Millwork decisions significantly affect both aesthetics and long-term functionality.
Lesson 4 • Textiles and Soft Furnishings
Examines fabric construction, fibre content, performance ratings, and upholstery standards. Textile selection affects durability, comfort, and the overall sensory quality of a space.
Lesson 5 • Wall Treatments and Surfaces
Covers paint, wallcovering, panelling, tile, and plaster as wall finish options. Each treatment carries distinct installation, maintenance, and acoustic implications.
Chapter 6HideHide detailsSee detailsLighting Design Fundamentals
Lighting Design Fundamentals
Lesson 1 • Natural Light and Daylighting Strategies
Analyses window orientation, glazing types, and shading devices to optimise daylight. Effective daylighting reduces energy use and improves occupant well-being.
Lesson 2 • Light and Its Properties
Explains colour temperature, colour rendering index, lumens, and lux as measurable lighting qualities. These metrics guide fixture selection and placement decisions.
Lesson 3 • Artificial Lighting Types and Fixtures
Surveys ambient, task, accent, and decorative lighting categories and their fixture types. Matching fixture type to function is essential for effective lighting design.
Lesson 4 • Lighting for Specific Space Types
Applies lighting principles to kitchens, bathrooms, retail, and hospitality environments. Each space type has unique task requirements and atmospheric goals.
Lesson 5 • Layered Lighting Design
Combines ambient, task, and accent layers into a cohesive lighting plan for each room. Layering provides flexibility and supports multiple activities within one space.
