Acquisition Yield



25 King embodies one of IIG’s key theories of change for real estate – to invest in buildings developed to Australian and world-leading environmental and indoor environment quality standards. This will help to reduce our carbon footprint, promote sustainable cities and communities, and improve health and wellbeing.

Environmental Performance

25 King is expected to achieve 6 Star GreenStar ‘Design and As Built’ ratings, placing it amongst the leading office buildings nationally to reach the highest level of environmentally sustainable design and construction. It is targeted to achieve a 5 Star NABERS energy and 4 Star NABERS water rating. As always, our property team will work closely with all tenants to continuously improve the performance of the building.

Design & Construction

25 King’s construction incorporates innovative engineered timber, cross-laminated timber (CLT) and Glulam, that contain up to 40% less embodied carbon than typical construction materials.

The design maximises connections with the surrounding development through several innovative features and practices, including the incorporation of the ‘Queenslander’ vernacular and references to the historic Royal National Agricultural & Industrial Association pavilions.

Contribution to health & wellbeing

The extensive use of exposed timber in the internal workspaces is intended to produce a natural aesthetic to enhance the health and wellbeing of building occupants. Studies by Planet Ark have identified that wooden interiors contribute to “improvements to a person’s emotional state and level of self-expression, reduced blood pressure, heart rate and stress levels, and improved air quality through humidity moderation.”

Lendlease’s tenancy marketing promotes “a natural aesthetic that enhances health and wellbeing of teams, and ultimately boosts productivity [and] a sense of space and connectedness that infuse the working areas of the building”.
