Planning rules for private open space

Private open space is any outdoor area used exclusively by occupants of a dwelling.

It encourages indoor-outdoor living opportunities and works best when integrated into the overall design of the building.

It can include any of the following:

  • backyard
  • deck
  • balcony
  • terrace or courtyard
  • front garden
  • pool area.

Private open space must meet certain rules within the Northern Territory (NT) Planning Scheme 2020.

The amount of private open space required for a dwelling will depend on the lot size and the dwelling type. For example, a dwelling-single on a 600m2 lot or an apartment on level 3 of a building.

Other things to consider

Other factors you might need to consider for your dwelling include whether the private open space is:

  • directly accessible
  • permeable
  • open to the sky.

Directly accessible

This is when you can step from the dwelling into the private open space area. This is the most effective way of extending the function of the dwelling and creating an indoor-outdoor living space.

Private open space is best located when it is directly accessible from more than one indoor space, such as a lounge room and bedroom.

Permeable

This is when plants and water can directly access the ground.

At least half of the required private open space for a ground level dwelling needs to be permeable. This allows for in-ground plants and trees for shade and amenity.

Having more private open space as permeable rather than concrete or pavers will also reduce stormwater runoff from the lot.

Open to the sky

Most grasses, plants and trees need natural light and space to grow.

A minimum area of private open space for ground level dwellings needs to be open to the sky and not covered by a roof, patio, verandah or shade sail.

Having more private open space open to the sky and landscaped will also reduce stormwater runoff from the lot.

Private open space must be all of the following:

  • open to the sky
  • mainly permeable to:
    • allow stormwater infiltration and
    • reduce the runoff from the site
  • appropriately sited to extend the function of the dwelling
  • of adequate size to provide for domestic uses and outdoor living activities
  • inclusive of areas for landscaping and tree planting.

If the minimum private open space is not provided, you will need a development permit if your development would otherwise be permitted. Read more about assessment categories and your planning and building responsibilities.

Private open space must:

  • meet the minimum dimensions
  • be appropriately sited to extend the function of the dwelling
  • suitably screened from adjacent dwellings with planting or fencing.

Private open space for a dwelling-multiple (apartment) can be at ground level, a balcony or on the podium level of a high-rise building.
