25 King has achieved a 6 Star Green Star Design and As-Built v1.1 rating and is believed to be the world’s first timber building and Queensland’s first building to receive a Platinum WELL Core and Shell Certification. The International Well Building Institute’s WELL Building Standard is the premier standard focused on enhancing people’s health and wellness across seven areas of building performance – air, water, light, nourishment, fitness, comfort and mind.
Comprising renewable cross-laminated timber walls and floors and glue-laminated timber structural beams and columns from floors one to nine, 25 King was designed and engineered with holistic sustainability and wellbeing as a priority. A highly sustainable model, with rooftop solar, rainwater capture and 74 per cent saving of embodied carbon, the building has also achieved a 46 percent reduction in energy and 29 percent reduction in potable water consumption.
Research has shown timber in indoor environments reduces stress and promotes health, satisfying the innate tendency to seek connections with nature. Biophilic design principles were employed throughout the design, expressed in the warmth of exposed timber surfaces, natural light and abundance of living greenery.
