Thiess is a leading Australian construction, mining and services contractor. In 2011 they leased three floors of office space in Coronation Drive Office Park to consolidate their teams currently located in two separate offices.

This fitout project was part of a strategic move by Thiess management who wanted to use the latest design trends to create an Activity-Based Workplace for their staff, moving from a traditional office layout to an open plan configuration. Priority designed and built their fitout, delivering a highly successful outcome for Thiess.

When an opportunity presented itself a couple years later for Thiess to lease an additional level in the building they jumped at the chance, planning to sublease a portion of this space initially, secure in the knowledge that their team would have room to grow in the future.

When Thiess initially moved to 143 Coronation Drive, our team cut a 5-metre square hole in the floor plate between levels 4 and 5 and constructed an architectural feature staircase, providing a physical and visual link between the levels that encourages active movement among team members. We continued the staircase down to level 3 as well; so all three floors are now conveniently accessible without relying on the lift.

Level 3 is currently sub-divided into two distinct tenancies with compatible designs that can later be combined. Either separate or combined, the overall environment is efficient and modern, and encourages team communication.

The overall design incorporates small open breakout areas where colleagues can informally interact. Scattered throughout the office are rooms of various sizes that can function as small meeting rooms as well as open up to accommodate larger groups. Each level has a large staff kitchen located on the river side of the tenancy so views are available to all staff. These spaces are bright and energetic, incorporating a variety of seating options.

Site safety is of utmost importance to both Thiess and Priority and both projects required precise attention to all safety and quality standards. Each office was completed on time and provides Thiess with a friendly, open, modern office environment where their team has room to grow and change as future opportunities present.
