Heralding a new dawn for sustainably designed, lifestyle-focused office accommodation in Sydney's north-west, 2 Castle Street is creating new possibilities for work and life in The Hills.
The design for 2 Castle Street combines wellbeing-oriented biophilic design and leading-edge mass timber construction techniques to redefine the workplace for a new generation. Conceived by world-renowned architect firm BVN, the building features a cross-laminated timber structure and a faade shrouded in native Australian plant species. 2 Castle St is set to become a true expression of time and place. Functional, indoor-outdoor design responds to today's changing work style with versatility and flexibility, providing opportunities to connect with nature and the region's natural beauty.
