Colour Theory and Application

  • Lesson 1 • Selecting and Presenting Colour Palettes

    Covers sampling, testing under varied lighting, and assembling client-ready colour boards. Bridges theory to deliverable outputs used in professional practice.

  • Lesson 2 • Understanding the Colour Wheel

    Explains hue, value, saturation, and the relationships between primary, secondary, and tertiary colours. Provides the vocabulary needed for all colour decision-making in design.

Space Planning and Layout

  • Lesson 1 • Measuring and Documenting Spaces

    Teaches field measurement techniques and accurate as-built documentation. Precise measurements prevent costly errors during furniture selection and installation.

  • Lesson 2 • Furniture Layout Strategies

    Covers conversation groupings, focal-point anchoring, and multi-use arrangements. Students produce multiple layout options and select the best solution for each scenario.

  • Lesson 3 • Space Planning for Specific Rooms

    Applies layout principles to living rooms, bedrooms, kitchens, and home offices. Reinforces chapter skills through room-specific constraints and best practices.

  • Lesson 4 • Traffic Flow and Circulation

    Analyses how people move through spaces and establishes clearance standards for safety and comfort. Students apply circulation principles to optimise room layouts.

  • Lesson 5 • Reading and Drawing Floor Plans

    Introduces architectural drawing conventions, scale, and standard symbols. Students hand-draft and interpret floor plans as the basis for all layout decisions.

Chapter 4See details

Light and Lighting Design

  • Lesson 1 • Layered Lighting Approach

    Introduces ambient, task, and accent lighting as complementary layers that together create flexible, functional spaces. Students design layered plans for sample rooms.

  • Lesson 2 • Artificial Lighting Types and Sources

    Covers incandescent, fluorescent, LED, and specialty sources with their colour rendering and efficiency profiles. Provides the technical foundation for informed fixture selection.

  • Lesson 3 • Lighting Plans and Specifications

    Teaches how to draw reflected ceiling plans and write fixture schedules. Connects lighting design decisions to construction documents used by electricians and contractors.

  • Lesson 4 • Natural Light in Interiors

    Examines how orientation, window size, and glazing affect daylight quality throughout the day. Students learn to maximise natural light while controlling glare and heat gain.

Chapter 5See details

Materials, Finishes, and Visual Textures

  • Lesson 1 • Building a Finish Schedule

    Teaches how to organise all material selections into a room-by-room finish schedule. This professional document communicates specifications clearly to contractors and clients.

  • Lesson 2 • Flooring Materials and Selection

    Compares hardwood, tile, carpet, vinyl, and concrete for performance and visual impact. Students match flooring to room function, traffic level, and design concept.

  • Lesson 3 • Countertops, Cabinetry, and Hardware

    Evaluates stone, solid surface, laminate, and wood countertops alongside cabinet construction and hardware finishes. Focuses on kitchen and bath applications where material performance is critical.

  • Lesson 4 • Textiles and Soft Furnishings

    Covers fabric construction, fibre content, durability ratings, and pattern matching for upholstery and window treatments. Textiles add tactile richness and acoustic benefit to spaces.

  • Lesson 5 • Wall Treatments and Finishes

    Explores paint, wallcovering, panelling, tile, and plaster as wall finish options. Students select treatments that reinforce the design concept and meet practical requirements.
