2521 - Judd Street



The re-development of an existing Edwardian office building with a new two-storey RC extension and extensive internal alterations including a new a re-configured central core to deliver a new lab enabled workspace.

  • Key Features:
  • Re-coring and extension of an iconic, early 1900’s office building.
  • Roof extension constructed using reinforced concrete to maximise flexibility and reduce embodied carbon of the new construction.
  •  New piled raft foundation utilised to support the new extension loads while maintaining the existing foundations and structure.
  •  Structure designed to be ‘lab enabled’ with minimal adaption works required by the tenant to allow use as a wet lab.
  • • Lab spaces designed to limit resonant response factor to less than 1 for 65% of the floorplate.
  • • Retained steel frame structure to the lower floors to minimise embodied carbon and maximise reuse.
  • • Exposed concrete finishes to the new RC structure, with columns and beams strengthened to accommodate an increased imposed load and vertical extension.
