Woods Bagot and SHoP Architects (United States) collaborated on the design, which suits the site and location and demonstrates a true interrelationship of both a world-leading sustainable design and a commitment to providing WELL Standard premises for all occupants, including staff. The WELL Building Standard is a performance-based system for measuring, certifying, and monitoring features of the built environment that impact human health and wellbeing, through air, water, nourishment, light, fitness, comfort, and mind.

Tetra Tech’s role encompassed mechanical, electrical, plumbing, hydraulics and vertical transportation design, development of a specialist fire engineering solution, and commissioning management advisory.
