Glasshouse, Macquarie

Client: John Holland
Architect: Architectus
Status: Complete

enstruct provided structural engineering services for The Glasshouse, a 9 storey 38,500sqm NLA commercial building with an expansive, light-filled central atrium and additional amenities in the form of retail and carparking areas. This prime grade building contains flexible workspaces and targeted a 5 Green Star rating and a 5 Star NABERS rating and is the first of five buildings John Holland's Macquarie Square development at Macquarie Park. 

An economical structural system of post-tensioned banded slabs was selected for the project and constructed efficiently using metal deck formwork to reduce cycle times. The structural grid was coordinated to incorporate commercial, carpark and retail use whilst allowing for a curvilinear profile to the central atrium. The atrium roof was designed and constructed using a steel composite structure to minimise falsework in the atrium. Lateral stability for the structure was achieved with a combined concrete core and moment frame system, allowing the main lift structure through the atrium to be exposed with glass lifts, enhancing the building space. An elegant lightweight cantilevered structural solution was used to allow the glass lifts to experience uninterrupted exposure to the atrium space.

enstruct also provided structural and civil engineering services for the Macquarie Square site assisting John Holland through their successful bid phase and aided with the required approvals regarding the adjacent rail easement.
