PPOS / Landscaped Areas / Floor Area / Site Coverage
This section focuses on three main calculations that any granny flat needs to show that it complies with, Principal Private Open Space (PPOS), Landscaped Areas, Site Coverage and Floor Areas.
Principal Private Open Space
The granny flat must show to have an outside entertainment area (e.g. usable backyard) that is at least 24sqm and that itβs directly accessible from a living room.
Landscaped Areas
This depends on your block size the following landscaped areas e.g. (turf & gardens) must be met;
Block (sqm) | Landscaping Areas |
450-600m2 | 20% |
600-900m2 | 25% |
900-1500m2 | 35% |
1500m2+ | 45% |
Note: 50% of the above must be behind the main dwelling (house)
Floor Areas
The following areas are the maximum floor area (inc garages, carports etc) calculated by combining the sqm area for both your existing home, (both levels if applicable) and the proposed granny flat.
Block (sqm) | Floor Area |
450-600m2 | 330m2 |
600-900m2 | 380m2 |
900m2+ | 430m2 |
Site Coverage
Site coverage differs from floor area as this calculation seeks to limit how much site is covered by built-up area. For instance a two storey building may have more floor area, but less site coverage than say a one storey building. The following table shows the maximum site coverage;
Block (sqm) | Floor Area |
450-600m2 | 330m2 |
600-900m2 | 380m2 |
900m2+ | 430m2 |
Summary
Block (sqm) | Frontage | Site Cover | Floor Area | Height | Front Setback | Side Setback | Rear Setback | Landscape Area |
450-600 | 12m | 50% | 380m2 | 8.5m | 4.5m | .9m | 3m | 20% |
600-900 | 12m | 50% | 380m2 | 8.5m | 4.5m | .9m | 3m | 25% |
900-1500 | 15m | 30% | 430m2 | 8.5m | 6.5m | 1.5m | 5m | 35% |
1500m2+ | 18m | 30% | 430m2 | 8.5m | 10m | 10m | 10m | 45% |
*note: front setbacks still need to be the average setback of the closest two properties fronting the same principal rd or the above minimum whichever the greater.
