Tips on good practices - Calculation plan presentation

15 May 2007

  • Verge all areas in 2 distinct colours:

    • Green for GFA

    • Red for non-GFA

  • Annotate GFA parcels clearly using:

    • Upper case letter (e.g. “A”) for green parcels

    • Lower case letter (e.g. “a”) for areas to be excluded from GFA within the green parcels

  • Group as many green areas within one parcel as possible (i.e. do not break up the green areas into too many smaller parcels)

Note: All Best Practice articles are only for general information. We strongly advise readers to read the relevant circulars we issue to professional institutes for full and accurate information on development control matters as these will continue to take precedence.
