  • Requirements: Clear, well-organised layout, with good use of lines, weights and hatches, and text.
  • Planning: Plan the structure, content and presentation of the boards.
  • Inspiration: Use relevant precedents, graphic styles, and consistency.
  • Architecture representation: Communicate ideas and essential aspects of the scheme clearly.
  • Clarity: Prioritise quality over quantity, consider a simple layout and use of relevant visuals.
  • Layout options: Use of grids, proper placement of elements, maintain a clear hierarchy.

Chapter Seven: Plans

  • Introduction: Provide essential information for a planning phase or construction.

  • Basic Floor plan requirements: showing walls, openings, doors and windows, grids, relevant internal parts.
  • Construction Drawings: Providing more detailed information regarding the construction process.
  • Floor plan labelling: Provide labels for rooms, walls, and objects of the plan.
  • Important Information on plans: Showing north, scales, and entrance points

Chapter Eight: Elevations and Sections

  • Introduction: To explain the differences between Elevations and Sections.
  • Elevations: Vertical representation of surfaces (external – like facades or internal – like walls).
  • Sections: Vertical representation of a 2D cut within a 3D space.
  • Information required in Elevation Drawings: The important elements and components within an elevation must be shown clearly, with relevant details including dimensions, materials, and finishes.
  • Information required in Section Drawings: Showing the relationships between levels, ceilings, walls, and other components

Chapter Nine: Construction Drawings

  • Introduction: Detail drawings to further communicate the design and construction process
  • Purpose: To provide all the necessary information required for the construction.
  • Important Elements of Drawings: Detailed drawings of walls, doors, windows, fixtures, fittings, and other key parts.
  • Schedules: A schedule provides details, dimensions, locations, finishes, and other associated information for construction of doors or windows.

General Information for all Chapters

  • Title Blocks: Consistent title blocks throughout the drawings.
  • Image Use: Use high-impact images to improve visual understanding.
