RFI Item 6: Species Selection - Commercial Availability
Provide information of the commercial availablilty of the proposed plant species especially the climbing plants and,
where not available, alternative species to be engaged.

Response:
• The Plant Schedule has been cross referenced with an online plant locator to ensure availablilty at local nurseries,
   all unavailable plants have been removed.
• Fytogreen Australia have reviewed the species list and commented on the commercial availablilty and and success
   of each species. All unsuitable species have been removed.

RFI Item 6: Green Walls - Exposure of Under Surface
Provide detail on the colour of the under surface to the green walls to ensure the development meets the material
change of use condition for the external colours and finishes of the building to comprose muted/environmental tones
that blend with the environment.

Response:
• Noel Robinson Architects have specified plain grey concrete as the under surface to the green walls. This finish will
   provide a suitable, muted appearance should climbing plants fail and temporarily expose the building. Refer to the
   images below for an example of the proposed finishes.
• We note that for green wall types 1 and 2, multiple species of climbing plants have been specified and will be
   planted/ mixed randomly to minimise dead patches due to plant failure or ill health. Green wall type 3 is a modular
   panel system for which the species selection uses a combination of native and exotic species that have been
   proven suitable and successful in similar residential courtyard projects. Species will be zoned according to climatic
   conditions with specific quantities and locations determined on site at the time of installation.
• The proposed maintenance program by the nominated supplier, Fytogreen Australia (refer to Item 7), will effectively
   reduce the occurance of dead patches and the exposure of the under surface. Species that are not performing well
   can be easily replaced as required.

RFI Item 7: Green Walls - Management and Maintenance
Provide a Management and Maintenance Guide for the household use that addresses expected management issues
associated with this emerging discipline.

Response:
• Fytogreen Australia have been nominated as the supplier/instlaller for all green roofs and green walls in this project.
   Fytogreen have designed and installed more than 95 successful vertical gardens and green roofs in Australia since
   2007. Fytogreen guides the project through design development, project management, supply, planting, and
   on-going maintenance. Fytogreen’s design team focuses on an ecologically-based design to ensure sustainable
   gardens are provided with minimal on going maintenance.
• A draft typical Green Wall / Green Roof Management and Maintenance Guide prepared by Fytogreen Australia is
   attached to this letter. We note that a site specific manual will be prepared post installation and provided to the
   homeowner at handover.
