In cooperation with

Greenwich Wharf London

Green Roofs were created and connected to lower level podium decks, making valuable use of the space available to store more water – whilst making places for a more pleasant environment where people can relax and enjoy whilst attracting wildlife and helping to clean and cool the surrounding air.

A closer look at this build-up at the Greenwharf in London

Once a derelict and unusable site of old warehouse buildings and hard surfaces, the multi-million pound Greenwich Wharf, with its mix of affordable homes, exclusive apartments, restaurants, a hotel, leisure centre and commercial/retail premises for local businesses, is now a vibrant, inviting and valuable piece of real estate.

Using our Permavoid Geocellular system, the site is able to sustain its own Green Infrastructure whilst controlling the discharge of store water at a controlled rate, providing Greenwich Wharf with a healthier more resilient future.


Mitigate any flood risks

With a scheme of this size, especially riverside, rainwater management needed to be of paramount importance, and our design partner EPG, worked with the developer and their design team, to devise a system that not only made space for water within clever podium decks, but also helped inject important Green Infrastructure – bringing a sense of community, wellbeing and calm to the new environment.

"Water is our most precious resource and should never be spilled."


Multifunctional blue-green roof System

The hollow Permavoid subbase makes it possible to store more rainwater in lightweight geocellular units underneath the soil in podium decks, blue-green roof systems and roof gardens. This stored rainwater is made available to the plants by capillary rise through capillary fibre columns in the Permavoid units. This nature- based solution of capillary irrigation eliminates the need for drip lines, valves, hoses, pumps and the associated maintenance requirements. Water is available for the plants when they need it, naturally, on-demand, and most importantly without the use of energy; just like in nature.

Water is the key to successful green infrastructure at any level, in every green design. Keep rainwater out of the sewer and put it to work to support, biodiversity and help cool the urban environment.
