Proposed citywide amendment - rooftop gardens and landscaped greenspace - Major amendment package G

Brisbane is a great place to live, work and relax. To ensure our friendly and liveable city continues to thrive and Brisbane City Plan 2014 (City Plan) remains effective and up-to-date, Brisbane City Council is proposing changes to some of its citywide provisions with the rooftop gardens and landscaped greenspace amendment (Major amendment package G).

Through amendments to City Plan, Council ensures planning decisions continue to reflect principles developed with community input, including creating and protecting greenspace.

The proposed amendment includes changes across a range of citywide provisions to:

  • encourage the provision of rooftop gardens by allowing those that achieve required standards to be excluded from the calculation of maximum number of storeys in medium to high density locations supporting residential, commercial and mixed use multi-storey developments
  • ensure rooftop gardens are integrated in the overall design of buildings, support a green building appearance and enhance the presentation and visual amenity of rooftops and the skyline
  • ensure where landscaping is proposed in rooftop gardens and other artificial growing environments (such as green roofs and green walls on buildings), City Plan standards are appropriate to ensure the successful delivery, maintenance and performance of landscaping over the long term.

This proposed amendment package is following the ‘major amendment’ process as outlined in the Queensland Government's Minister's Guidelines and Rules. 

Community consultation

Public consultation on the proposed amendment package has closed. 

Council's proposed amendment package was open for public consultation from 16 November to 13 December 2020.

Proposed changes

Changes to the following parts of City Plan are proposed to give effect to these outcomes:

  • Rules about determination of maximum building height
  • Centre or mixed use code
  • Multiple dwelling code
  • Retirement and residential care facility code
  • Brisbane City Council administrative definitions.

Supporting changes ensure where landscaping is proposed in rooftop gardens and in other artificial growing environments (such as green roofs and green walls on buildings), City Plan standards are appropriate to ensure the successful delivery, maintenance and performance of landscaping over the long term. 

Supporting changes are proposed to the following parts of City Plan:

  • Filling and excavation code

The proposed changes include changes to development codes and associated planning scheme policies to support high-quality design outcomes for rooftop gardens. Only rooftop gardens that meet required standards will be excluded from the calculation of maximum number of storeys in the relevant zones. 

Relevant standards include:

  • communal open space requirements
  • extent of landscaping
  • supported types of rooftop structures including maximum footprint, height and setbacks.

The changes for rooftop gardens also include new provisions to ensure rooftop gardens:

  • are integrated as part of the overall architectural design of buildings
  • support a green building appearance and enhance the presentation and visual amenity of the rooftop and skyline.

For the identified zones, a rooftop garden will not count as a storey for the purpose of calculating maximum storeys where meeting the following key standards:

  • providing communal open space, and not providing private open space
  • providing a minimum 15% of the rooftop as landscaping or 0.75 times the footprint of rooftop structures – whichever is greater
  • rooftop structures with solid roofs are limited to 30% of the rooftop area – unroofed pergolas, gazebos and other similar structures can continue to provide additional permeable shelter as long as minimum landscaping requirements are met
  • structures higher than 3.5m are set back from the perimeter of rooftops and limited to a maximum height of 6m.

Proposed changes to the Landscape work code and supporting planning scheme policies

Read more

The changes to the Landscape work code and planning scheme policies focus on ensuring that where landscaping in any artificial growing environments is proposed, the development can deliver and maintain intended functional and visual outcomes over the long term.

This includes outcomes and standards around the design, growing media, planting species, irrigation and maintenance as well as supporting guidance in the planning scheme policies, including broader design and construction considerations that are integral to demonstrating successful outcomes.
