    Traces interior design from ancient dwellings to contemporary practice. Establishes historical context that informs modern aesthetic and functional decisions.

  • Lesson 3 • Professional Roles and Ethics

    Defines the interior designer's scope of practice, client relationships, and ethical obligations. Sets professional expectations for all subsequent project work.

  • Lesson 4 • Elements of Interior Space

    Defines line, form, texture, pattern, and space as design elements. Students apply each element to real room scenarios for immediate practice.

  • Lesson 5 • Core Design Principles

    Introduces balance, rhythm, emphasis, harmony, and proportion. These principles form the evaluative lens used throughout the entire course.

Space Planning and Layout

  • Lesson 1 • Space Planning for Specific Room Types

    Applies planning principles to living, dining, kitchen, bedroom, and bath spaces. Students produce annotated layouts for each room type.

  • Lesson 2 • Reading and Drawing Floor Plans

    Teaches plan-view conventions, symbols, and scale drawing techniques. Students translate measured spaces into accurate, readable floor plans.

  • Lesson 3 • Zoning and Functional Areas

    Groups activities into public, private, and service zones within a plan. Proper zoning reduces conflict between incompatible uses.

  • Lesson 4 • Traffic Flow and Circulation

    Analyses primary, secondary, and service circulation paths within a space. Optimising flow prevents congestion and improves daily usability.

  • Lesson 5 • Understanding Human Scale and Ergonomics

    Applies anthropometric data to furniture sizing and clearance standards. Ensures layouts accommodate diverse users comfortably and safely.

Chapter 3See details

Materials, Finishes, and Textures

  • Lesson 1 • Wall Finishes and Coverings

    Surveys paint, wallcovering, panelling, tile, and plaster as wall finish options. Finish choice affects acoustics, maintenance, and spatial perception.

  • Lesson 2 • Textiles and Soft Furnishings

    Covers fabric weaves, fibre content, performance ratings, and upholstery grades. Textile selection balances comfort, durability, and design intent.

  • Lesson 3 • Flooring Materials and Selection

    Compares hardwood, engineered wood, tile, stone, carpet, and resilient flooring. Selection criteria include durability, maintenance, acoustics, and cost.

  • Lesson 4 • Ceiling Treatments and Materials

    Explores flat, coffered, vaulted, and suspended ceiling systems and their finishes. Ceiling design affects perceived height, acoustics, and lighting integration.

  • Lesson 5 • Sustainable and Healthy Materials

    Evaluates materials for environmental impact, indoor air quality, and lifecycle cost. Students apply green criteria to material specification decisions.

Chapter 4See details

Lighting Design Fundamentals

  • Lesson 1 • Fixture Types and Placement

    Covers recessed, surface, pendant, track, and wall-mounted fixtures and their applications. Correct placement maximises coverage and minimises shadows.

  • Lesson 2 • Natural Light and Daylighting

    Analyses window orientation, glazing, and shading to optimise daylight use. Effective daylighting reduces energy use and improves occupant well-being.

  • Lesson 3 • Layers of Lighting

    Defines ambient, task, accent, and decorative lighting layers and their roles. Combining layers creates flexible, visually rich interior environments.

  • Lesson 4 • Light Sources and Lamp Types

    Compares incandescent, fluorescent, LED, and specialty light sources by output and efficiency. Understanding source characteristics drives appropriate fixture selection.

  • Lesson 5 • Lighting Controls and Energy Efficiency

    Introduces dimmers, occupancy sensors, timers, and smart lighting systems. Controls extend lamp life, reduce energy consumption, and enhance user comfort.

Chapter 5See details

Interior Architecture and Building Systems

  • Lesson 1 • Mechanical, Electrical, and Plumbing Basics

    Introduces HVAC, electrical, and plumbing systems as they affect interior layout. Designers must coordinate with trades to avoid conflicts and ensure comfort.

  • Lesson 2 • Building Codes and Permit Processes

    Explains occupancy classifications, egress requirements, and permit submission steps. Code compliance is non-negotiable and protects occupant safety.

  • Lesson 3 • Doors, Windows, and Openings

    Covers door and window types, swing clearances, and rough opening requirements. Proper specification ensures code compliance and smooth installation.

  • Lesson 4 • Accessibility and Universal Design Standards

    Applies functional accessibility standards to circulation, fixtures, and controls. Universal design benefits all users and is required in many project types.

  • Lesson 5 • Structural Elements and Load-Bearing Walls

    Identifies load-bearing walls, columns, beams, and their impact on spatial modification. Recognising structural limits prevents costly and unsafe design errors.

Chapter 6See details

Furniture Selection and Arrangement
