Design Considerations
Gable/Curved Units Attached Between a Flat Unit & an Existing Structure
Gable/Curved Units which are attached between a Flat Unit (excluding pergolas) and an existing house, shall only be considered attached if the Gable/Curved Unit is attached to the existing house (C) for its full length (L) and the longest side of the combined unit (B) does not exceed twice the gable/curved length (L). The Flat Unit in this case can be considered attached. This style requires all columns to be embedded into footings.
Gable/Curved Units Attached to Flat Unit One or Both Sides
Gable/Curved Units which are attached one or both sides to Flat Units, (excluding pergolas) must be attached to an existing house for at least 75% of the gable/curved opening length (O) to be considered attached. Flat Unit/s must be deemed attached as detailed in the Flat Unit section below to allow the Gable/Curved Unit to be considered attached.
Gable/Curved Units are considered attached both sides if both Flat 1 and 2 comply with attachment rules for Flat Units as detailed below. Gable/Curved Units are considered attached one side if only one Flat Unit exists and it complies with the attachment rules for Flat Units as detailed below.
Flat Units
A Verandah, Patio, Carport or Pergola is deemed to be freestanding unless it is attached to an existing house (C) for at least 75% of the length of its shortest side (A), and its longest side (B) does not exceed twice the length of its shortest side.
Design Options
When designing an Outback, consideration should be given to both roof sheet direction, and the orientation of any openings and overhangs involved. These are often determined by appearance and drainage requirements. The following shows some of the normal options used.
Attached to Flat Unit One Side & Wall or Fascia One End
Attached Both Sides to Flat Unit & Wall or Fascia Opposite Side
Attached to Flat Unit Both Sides & Wall or Fascia One End
