    Teaches standard architectural drawing conventions, scales, and symbols used in floor plans. Accurate plan reading is prerequisite to all layout and specification work.

  • Lesson 2 • Furniture Arrangement Strategies

    Presents zoning, traffic flow, and conversation grouping methods for diverse room types. Students test multiple layouts before selecting the most functional solution.

  • Lesson 3 • Space Planning for Commercial Environments

    Addresses occupancy loads, egress requirements, and workstation density in office and retail contexts. Applies regulatory minimums to produce compliant commercial layouts.

  • Lesson 4 • Producing Schematic Floor Plans

    Guides students from bubble diagrams through refined schematic plans using manual and digital methods. Produces a documented layout ready for client review.

  • Lesson 5 • Human Factors and Ergonomics

    Applies anthropometric data and ergonomic standards to determine clearances, reach zones, and furniture sizing. Ensures spaces accommodate the full range of human body dimensions.
