Recently completed, the largest Modular Greenroof in Sydney

MEP Tray is essentially a shallow planter designed specifically for extensive planting over roof tops, it takes care of water storage, drainage and provides an environment for the plants to succeed.

At this project in Eastern Sydney, 500 MEP Trays cover 126m2 of exposed roof top.  Each MEP Tray stores up to 7 litres, that means the plants are sustained by 3500 litres of stored rainwater.  This massively reduces reliance on irrigation. Excess rainwater is drained via a network of drainage pipes.

4500 plants were planted on site, mainly succulents and grasses that will tolerate the exposed conditions.  As the plants grow the landscape will soften improving the view for anyone who overlooks the roof garden. A wildlife habitat will start to evolve providing a safe space for the birds and bees.


Research worldwide has shown that green roofs limit the impact of climate change underlining the valuable role they play in sustainable design.  They reduce heat transmission from rooftop to habitable space below, lower ambient temperature, mitigate urban heat islands, reduce run off and improve air quality and aesthetics.
