With experience across defence, space, civil, community, commercial and industrial sectors, it prioritises reliable, well-aligned projects. Bennett Architecture has a long-standing partnership with Sitzler, including delivery of its Darwin headquarters. The proposed development consolidates operations at Pruen Road by amalgamating Lots 98 and 100, replacing existing buildings with a new secure headquarters.

Project Story
Sitzler is a Northern Territory–based constructor operating nationally as a Tier One delivery partner, delivering high-profile infrastructure projects across Australia. As a multibillion-dollar organisation, Sitzler possesses the capability and resources to deliver comprehensive construction solutions nationwide.
With a strong track record spanning defence, space, civil infrastructure, community, commercial, and industrial sectors, Sitzler focuses on projects aligned with its proven expertise and capacity—prioritising reliability while avoiding overextension.
Bennett Architecture has established a long-standing relationship with Sitzler, having collaborated on multiple design and construct projects, including the delivery of their new Darwin headquarters.
Following an assessment of several potential locations, Sitzler elected to consolidate its operations at Pruen Road, where it currently occupies three adjoining sites. The proposed development involves the amalgamation of Lots 98 and 100, demolition of the existing structure on Lot 98 to enable a new build, followed by the decanting and subsequent demolition of Lot 100.
The new headquarters will provide approximately 1,600m² of high-quality, secure office accommodation, incorporating both public and staff areas within a high-security environment. The design features 3.5-metre-high, double-glazed, shaded façade walls arranged around a central shaded courtyard, which is retained within the demolition footprint.
The site planning incorporates separate truck and vehicle access points, shaded parking, and high-quality landscaped surrounds. Internally, the building will deliver a premium fitout that showcases Sitzler’s capabilities while providing staff with flexible, engaging, and high-performance work environments.
