Natural Habitats responded to the brief with its bespoke eco-pillow system. Comprising an impressive 560 eco-pillows, these special planters measure 1000 x 500 x 120 mm and are the lightest green roof solution on the market. Being made from recycled polystyrene from Auckland’s waste stream, along with a special mix of growing media, plants can thrive at heights without the structural reinforcing which other green roofs require.

The impact on the environment for a project of this scale is significant. Green roofs filter air pollutants, help to reduce temperatures, mitigate stormwater runoff, and help to regulate the internal temperature of the building amongst many other benefits.
Ngāti Whātua Ōrākei completed the planting design, referencing a pattern known as “poutama” representing education, progress, and ascension. “It pays homage to the library as a place where people seek education, progress and ascension into greater knowledge and understanding,” says Ngāti Whātua Ōrākei artist Hinengarangi Makoare.
A project of this scale did not come without its challenges, being plagued by COVID-19 delays and seasonal extremes. Due to the delays, planting was pushed into the long dry summer of 2022 where young plants are challenged by lengthy sunlight hours. Due to the roof having loading limits, plants and materials were craned up in palettes in particular timings and quantities.
As the roof grows in, a range of benefits will be monitored, reported on and shared publicly to help others learn from this project. Natural Habitats will proudly complete the maintenance of this roof, caring for the plants and ensuring the integrity of the building waterproofing membrane and systems.
Watch as some of the key people behind the project, talk about its significance in the industry, and for Te Ao Māori.
