We advised Hassell Studio, Mirvac Construction and Ernst & Young on the installation of a 3.6m tree on the 35th floor of 200 George Street Sydney.


  • As the major tenant of 200 George Street, Sydney, Ernst & Young required a feature tree to be located on the 35th
  • As the building was still under construction this allowed a long lead time to secure and acclimatise the tree.

Outcome Required

  • Ernst & Young expected the successful installation of a 3.6m evergreen tree.
  • The tree to thrive and grow over the longer term (10 – 15 years)

Action Taken by IPT

  • advised the design architect on suitable indoor tree species
  • sourced and secured a suitable tree from the grower and advised on acclimatisation procedures
  • in collaboration with lighting engineer advised on supplementary light requirements and specified lamps
  • advised on a sub irrigated container (without drainage requirements) and nominated a supplier
  • prepared specifications and tender documents for the tree installation and maintenance
  • nominated a panel of suitable contractors for invitation to submit tenders
  • advised the client on tender compliance
  • oversaw successful tree installation
