The creative Amsterdam firm Hofman Dujardin Architects, in collaboration with Fokkema&Partners, has played a leading role in helping sustainable energy company Eneco to practise what it preaches. They have designed the interiors for Eneco’s headquarters building in Rotterdam, which has undergone a revolution to create the perfect working environment, complete with solar power, natural light and oxygen from internal vegetation, echoing Eneco’s vision of sustainability. Eneco’s new building is also the perfect example of how clever and efficient office design can offer employees the possibility to work flexibly in a dynamic, open, sustainable and healthy environment.
