• Good planning in architecture is not aimless but has a logical reason behind it called "a parti" or scheme
• A good plan should be organic, meaning that the composition will be disturbed if one element is moved
• A plan can be simple or complex depending on the use of the building
• Primary principles of plan composition include:

  • Contrast (size, shape, character, direction)
  • Balance (Symmetrical & unsymmetrical)
  • Emphasis
• Secondary principles of plan composition are:

  • Repetition
  • Alternation
  • Transition
  • Transformation
• Contrast is used to give interest or emphasis by producing differences in sizes of areas, variation of shapes, contrast in character, and contrast in direction
• Balance in architecture can be symmetrical (bilateral symmetry, radial symmetry) or unsymmetrical
• Visual emphasis in architecture can be achieved by endowing a form or shape with exceptional qualities, a unique shape, or a strategic location
• Transformation of form can involve dimensional transformation, subtractive transformation, and additive transformation
• Forms differing in geometry or orientation may be incorporated into a single organization for various reasons, such as accommodating interior space and exterior form, expressing functional or symbolic importance, or inflecting a space toward a specific feature of a building site
• Formal collisions of geometry can result in forms subverting their individual identities to create a new composite form, one form receiving the other totally within its volume, forms retaining their individual identities and sharing interlocking portions of their volumes, or forms separating and being linked by a third element recalling the geometry of one of the original forms
• The lecture discussed three types of transformation: dimensional transformation, subtractive transformation, and additive transformation, as well as formal collisions of geometry
• PLAN

  A guide to be a good planner
• The principles of plan composition are:

  1. Primary principles
  2. Secondary Principles
• Alternation – a synonym for contrast.
• Dimensional Transformation

  A form can be transformed by altering one or more of its

  dimensions and still retain its identity as a member of a family

  of forms.
• Subtractive Transformation

  A form can be transformed by subtracting a portion of its

  volume.
• Additive Transformation

  A form can be transformed by the addition of elements to its volume.
