    Introduces essential terminology used across all design disciplines. Accurate language enables precise communication with clients and collaborators.

Chapter 2See details

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 color wheel, color relationships, and psychological impact of hue, value, and saturation. Color 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 practice identifying and critiquing design decisions in existing spaces.

Chapter 3See details

Design Drawing and Visual Communication

  • Lesson 1 • Elevation Drawings, Sections, and Details

    Produces interior elevation drawings, 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 4See details

Space Planning and Functional Layout

  • Lesson 1 • Circulation and Traffic Flow

    Analyzes 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 livable 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 5See details

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.

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.
