Urban green rooftop
Van Oord thought hard about the roofs for its new head office at the foot of the Van Brienenoord Bridge in Rotterdam. The “Nieuwe Maas” (New Meuse) building has 4,800 m2 of moss sedum roofs and a 3,000 m2 hardwood rooftop terrace.
Moss sedum roof
Sedums are succulents. The plants have water-absorbing leaves. Therefore, Van Oord’s green roof has many advantages in economic, ecological and social terms. For example, our roof ensures water retention, air purification, a lower ambient temperature, heat regulation, energy saving and biodiversity in the city.
For all the economic, ecological and social advantages Van Oord was included in the Rotterdam Roofbook [Rotterdamse Dakenboek] that was published in 2017. The book is an enthusiastic, informative, and inspiring publication about the use of flat roofs in the city of Rotterdam. It takes 37 examples to illustrates how Rotterdam already uses roofs for rainwater (blue), nature (green), living, working, and recreation (red), and energy (yellow). It also provides a glimpse of future roof developments.
It’s a privilege to be the supervisor of this building. It feels like a second home for me – I’ve grown along with it from the initial ideas at the end of 2009. It’s a very spacious building, with 22,000 m2 for eight hundred employees. And it’s sustainable too: almost all the materials used can be fully recycled, and we also have a heat/cold storage system
